-# Installing Windshaft-CartoDB #
-
-## Requirements ##
-Make sure that you have the requirements needed. These are
-
-- Core
-  - Node.js >=0.8
-  - npm >=1.2.1 <2.0.0
-  - PostgreSQL >8.3.x, PostGIS >1.5.x
-  - Redis >2.4.0 (http://www.redis.io)
-  - Mapnik 2.0.1, 2.0.2, 2.1.0, 2.2.0, 2.3.0. See [Installing Mapnik](https://github.com/CartoDB/Windshaft#installing-mapnik).
-  - Windshaft: check [Windshaft dependencies and installation notes](https://github.com/CartoDB/Windshaft#dependencies)
-  - libcairo2-dev, libpango1.0-dev, libjpeg8-dev and libgif-dev for server side canvas support
-
-- For cache control (optional)
-  - CartoDB 0.9.5+ (for `CDB_QueryTables`)
-  - Varnish (http://www.varnish-cache.org)
-
-On Ubuntu 14.04 the dependencies can be installed with
-
-```shell
-sudo apt-get update
-sudo apt-get install -y make g++ pkg-config git-core \
-  libgif-dev libjpeg-dev libcairo2-dev \
-  libhiredis-dev redis-server \
-  nodejs nodejs-legacy npm \
-  postgresql-9.3-postgis-2.1 postgresql-plpython-9.3 postgresql-server-dev-9.3
-```
-
-On Ubuntu 12.04 the [cartodb/cairo PPA](https://launchpad.net/~cartodb/+archive/ubuntu/cairo) may be useful.
-
-## PostGIS setup ##
-
-A `template_postgis` database is expected. One can be set up with
-
-```shell
-createdb --owner postgres --template template0 template_postgis
-psql -d template_postgis -c 'CREATE EXTENSION postgis;'
-```
-
-## Build/install ##
-
-To fetch and build all node-based dependencies, run:
-
-```
-npm install
-```
-
-Note that the ```npm install``` step will populate the node_modules/
-directory with modules, some of which being compiled on demand. If you
-happen to have startup errors you may need to force rebuilding those
-modules. At any time just wipe out the node_modules/ directory and run
-```npm install``` again.

+**TILES**
+
+[GET] subdomain.cartodb.com/tiles/:table_name/:z/:x/:y.[png|png8|grid.json]
+
+Args:
+
+* sql - plain SQL arguments
+* interactivity - specify the column to use in UTFGrid
+* cache_buster - Specify an identifier for the internal tile cache.
+                 Requesting tiles with the same cache_buster value may
+                 result in being served a cached version of the tile

+                 timestamp value in cache_buster for manual control of
+                 updates.
+* geom_type - override the cartodb default
+* style - override the default map style with Carto
 
 
-Examples
---------
+**STYLE**
 
-[CartoDB's Map Gallery](http://cartodb.com/gallery/) showcases several examples of visualisations built on top of this.
+[GET/POST] subdomain.cartodb.com/tiles/:table_name/style
 
-Contributing
----
+Args:
 
-See [CONTRIBUTING.md](CONTRIBUTING.md).
+* style - the style in CartoCSS you want to set
+* style_version - the version of the style for POST
+* style_convert - request conversion to target version (both POST and GET)
 
-### Developing with a custom windshaft version
 
-If you plan or want to use a custom / not released yet version of windshaft (or any other dependency) the best option is
-to use `npm link`. You can read more about it at [npm-link: Symlink a package folder](https://docs.npmjs.com/cli/link).
+**INFOWINDOW**
 
-**Quick start**:
+[GET] subdomain.cartodb.com/tiles/:table_name/infowindow
 
-```shell
-~/windshaft-directory $ npm install
-~/windshaft-directory $ npm link
-~/windshaft-cartodb-directory $ npm link windshaft
-```
+Args:
+
+* infowindow - returns contents of infowindow from CartoDB.
+
+
+**MAP METADATA**
+
+[GET] subdomain.cartodb.com/tiles/:table_name/map_metadata
+
+Args:
+
+* infowindow - returns contents of infowindow from CartoDB.
+
+
+All GET requests are wrappable with JSONP using callback argument,
+including the UTFGrid map tile call.

-# Maps API
-
-The CARTO Maps API allows you to generate maps based on data hosted in your CARTO account and apply custom SQL and CartoCSS to the data. The API generates a XYZ-based URL to fetch Web Mercator projected tiles, using web clients such as [Leaflet](http://leafletjs.com), [Google Maps](https://developers.google.com/maps/), or [OpenLayers](http://openlayers.org/).
-
-You can create two types of maps with the Maps API:
-
-- **Anonymous Maps**  
-  You can create maps using your CARTO public data. Any client can change the read-only SQL and CartoCSS parameters that generate the map tiles. These maps can be created from a JavaScript application alone and no authenticated calls are needed. See [this CARTO.js example](/carto-engine/carto-js/getting-started/).
-
-- **Named Maps**  
-  There are also maps that have access to your private data. These maps require an owner to setup and modify any SQL and CartoCSS parameters and are not modifiable without new setup calls.

-# 1. Purpose
-
-This specification describes an extension for
-[MapConfig 1.4.0](https://github.com/CartoDB/Windshaft/blob/master/doc/MapConfig-1.4.0.md) version.
-
-
-# 2. Changes over specification
-
-This extension targets layers with `sql` option, including layer types: `cartodb`, `mapnik`, and `torque`.
-
-It extends MapConfig with a new attribute: `analyses`.
-
-## 2.1 Analyses attribute
-
-The new analyses attribute must be an array of analyses as per [camshaft](https://github.com/CartoDB/camshaft). Each
-analysis must adhere to the [camshaft-reference](https://github.com/CartoDB/camshaft/blob/0.8.0/reference/versions/0.7.0/reference.json) specification.
-
-Each node can have an id that can be later references to consume the query from MapConfig's layers.
-
-Basic analyses example:
-
-```javascript
-[
-    {
-        // REQUIRED
-        // string, `id` free identifier that can be reference from any layer
-        "id": "HEAD",
-        // REQUIRED
-        // string, `type` camshaft's analysis type
-        "type": "source",
-        // REQUIRED
-        // object, `params` will depend on `type`, check camshaft-reference for more information
-        "params": {
-            "query": "select * from your_table"
-        }
-    }
-]
-```
-
-# 2.2. Integration with layers
-
-As pointed before an analysis node id can be referenced from layers to consume its output query.
-
-The layer consuming the output must reference it with the following option:
-
-```
-{
-    "options": {
-        // REQUIRED
-        // object, `source` as in the future we might want to have other source options
-        "source": {
-            // REQUIRED
-            // string, `id` the analysis node identifier
-            "id": "HEAD"
-        }
-    }
-}
-```

-
-
-# 2. Changes over specification
-
-This extension depends on Analyses extension. It extends MapConfig with a new attribute: `dataviews`.

-## 3. Filters
-
-Camshaft's analyses expose a filtering capability and `aggregation` and `histogram` dataviews get them for free with
- this extension. Filters are available with the very dataview id, so if you have a "basic_histogram" histogram dataview
- you can filter with a range filter with "basic_histogram" name.
-
-
-## 3.1 Filter types
-
-### Category
-
-Allows to remove results that are not contained within a set of elements.
-Initially this filter can be applied to a `numeric` or `text` columns.
-
-Params
-
-```
-{
-    “accept”: [“Spain”, “Germany”]
-    “reject”: [“Japan”]
-}
-```
-
-### Range filter
-
-Allows to remove results that don’t satisfy numeric min and max values.
-Filter is applied to a numeric column.
-
-Params
-
-```
-{
-    “min”: 0,
-    “max”: 1000
-}
-```
-
-## 3.2. How to apply filters
-
-Filters must be applied at map instantiation time.
-
-With :mapconfig as a valid MapConfig and with :filters (a valid JSON) as:
-
-### Anonymous map
-
-`GET /api/v1/map?config=:mapconfig&filters=:filters`
-
-`POST /api/v1/map?filters=:filters`
-with `BODY=:mapconfig`
-
-If in the future we need to support a bigger filters param and it doesn’t fit in the query string,
- we might solve it by accepting:
-
-`POST /api/v1/map`
-with `BODY={“config”: :mapconfig, “filters”: :filters}`
-
-### Named map
-
-Assume :params (a valid JSON) as named maps params, like in: `{“color”: “red”}`
-
-`GET /api/v1/named/:name/jsonp?config=:params&filters=:filters&callback=cb`
-
-`POST /api/v1/named/:name?filters=:filters`
-with `BODY=:params`
-
-If, again, in the future we need to support a bigger filters param that doesn’t fit in the query string,
- we might solve it by accepting:
-
-`POST /api/v1/named/:name`
-with `BODY={“config”: :params, “filters”: :filters}`
-
-
-## 3.3 Bounding box special filter
-
-A bounding box filter allows to remove results that don’t satisfy a geospatial range.
-
-The bounding box special filter is available per dataview and there is no need to create a bounding box definition as
-it’s always possible to apply a bbox filter per dataview.
-
-A dataview can get its result filtered by bounding box by sending a bbox param in the query string,
-param must be in the form `west,south,east,north`.
-
-So applying a bbox filter to a dataview looks like:
-GET /api/v1/map/:layergroupid/dataview/:dataview_name?bbox=-90,-45,90,45

-# 1. Purpose
-
-This specification describes an extension for
-[MapConfig 1.3.0](https://github.com/CartoDB/Windshaft/blob/master/doc/MapConfig-1.3.0.md) version.
-
-
-# 2. Changes over specification
-
-This extension introduces a new layer type so it's possible to use a Named Map by its name as a layer.
-
-## 2.1 Named layers definition
-
-```javascript
-{
-    // REQUIRED
-    // string, `named` is the only supported value
-    type: "named",
-
-    // REQUIRED
-    // object, set `named` map layers configuration
-    options: {
-
-        // REQUIRED
-        // string, the name for the Named Map to use
-        name: "world_borders",
-
-        // OPTIONAL
-        // object, the replacement values for the Named Map's template placeholders
-        // See https://github.com/CartoDB/Windshaft-cartodb/blob/master/docs/Map-API.md#instantiate-1 for more details
-        config: {
-            "color": "#000"
-        },
-
-        // OPTIONAL
-        // string array, the authorized tokens in case the Named Map has auth method set to `token`
-        // See https://github.com/CartoDB/Windshaft-cartodb/blob/master/docs/Map-API.md#named-maps-1 for more details
-        auth_tokens: [
-            "token1",
-            "token2"
-        ]
-    }
-}
-```
-
-## 2.2 Limitations
-
-1. A Named Map will not allow to have `named` type layers inside their templates layergroup's layers definition.
-2. A `named` layer does not allow Named Maps form other accounts, it's only possible to use Named Maps from the very
-same user account.

-The Windshaft-CartoDB MultiLayer API extends the [Windshaft MultiLayer API](https://github.com/CartoDB/Windshaft/blob/master/doc/Multilayer-API.md) in a few ways.
-
-## Last modification timestamp embedded in the token
-
-It encodes a timestamp of 'last modification time' into the map token (token:EPOCH) returned to the client.
-It accepts tokens with encoded timestamp from the client considering the token suffix as a cache_buster value.
-
-Clients don't need to be aware of the extension but rather use the API as they would use the base one.
-The only difference will be that the _same_ layergroup configuration may result in different tokens if source data was modified between the mapview requests. 
-
-## Additional attributes in the response object
-
-Windshaft-CartoDB adds the following attributes in the response object
-
-- ``last_update`` field with ISO format (2013-11-30T12:23:10).
-- ``cdn_url`` object containing CDN url client should use (not mandatory) to access the tiles. It's in the form:

-   ```json
-   {
-     "http": "http://cdn_url.com/",
-     "https": "https://secure.cdn_url.com/"
-   }

-
-See [MapConfig File Formats](http://docs.carto.com/carto-engine/maps-api/mapconfig/) for details.
-
-#### Response
-
-The response includes:
-
-Attributes | Description
---- | ---
-layergroupid | The ID for that map, used to compose the URL for the tiles. The final URL is: `https://{username}.carto.com/api/v1/map/{layergroupid}/{z}/{x}/{y}.png`
-updated_at | The ISO date of the last time the data involved in the query was updated.
-metadata | Includes information about the layers.
-cdn_url | URLs to fetch the data using the best CDN for your zone.
-
-### Example
-

-    "http": "http://cdb.com",
-    "https": "https://cdb.com"
-  }
-}
-```
-
-### Retrieve resources from the layergroup
-
-When you have a layergroup, there are several resources for retrieving layergoup details such as, accessing Mapnik tiles, getting individual layers, accessing defined Attributes, and blending and layer selection.
-
-#### Mapnik tiles
-
-These tiles will get just the Mapnik layers. To get individual layers, see the following section.
-
-```bash
-https://{username}.carto.com/api/v1/map/{layergroupid}/{z}/{x}/{y}.png
-```
-
-#### Individual layers
-
-The MapConfig specification holds the layers definition in a 0-based index. Layers can be requested individually in different formats depending on the layer type.
-
-Individual layers can be accessed using that 0-based index. For UTF grid tiles:
-
-```bash
-https://{username}.carto.com/api/v1/map/{layergroupid}/{layer}/{z}/{x}/{y}.grid.json
-```
-
-In this case, `layer` as 0 returns the UTF grid tiles/attributes for layer 0, the only layer in the example MapConfig.
-
-If the MapConfig had a Torque layer at index 1 it could be possible to request it with:
-
-```bash
-https://{username}.carto.com/api/v1/map/{layergroupid}/1/{z}/{x}/{y}.torque.json
-```
-
-#### Attributes defined in `attributes` section
-
-```bash
-https://{username}.carto.com/api/v1/map/{layergroupid}/{layer}/attributes/{feature_id}
-```
-
-Which returns JSON with the attributes defined, like:
-
-```javascript
-{ "c": 1, "d": 2 }
-```
-
-#### Blending and layer selection
-
-```bash
-https://{username}.carto.com/api/v1/map/{layergroupid}/{layer_filter}/{z}/{x}/{y}.png
-```
-
-Note: currently format is limited to `png`.
-
-`layer_filter` can be used to select some layers to be rendered together. `layer_filter` supports two formats:
-
-- `all` alias
-
-Using `all` as `layer_filter` will blend all layers in the layergroup
-
-```bash
-https://{username}.carto.com/api/v1/map/{layergroupid}/all/{z}/{x}/{y}.png
-```
-
-- Filter by layer index
-
-A list of comma separated layer indexes can be used to just render a subset of layers. For example `0,3,4` will filter and blend layers with indexes 0, 3, and 4.
-
-```bash
-https://{username}.carto.com/api/v1/map/{layergroupid}/0,3,4/{z}/{x}/{y}.png
-```
-
-Some notes about filtering:
-
-  - Invalid index values or out of bounds indexes will end in `Invalid layer filtering` errors.
-  - Ordering is not considered. So right now filtering layers 0,3,4 is the very same thing as filtering 3,4,0. As this
-  may change in the future **it is recommended** to always select the layers in ascending order so you will get a
-  consistent behavior in the future.
-

-The JSONP endpoint is provided in order to allow web browsers access which don't support CORS.
-
-#### Definition

-## Remove
-
-Anonymous Maps cannot be removed by an API call. They will expire after about five minutes, or sometimes longer. If an Anonymous Map expires and tiles are requested from it, an error will be raised. This could happen if a user leaves a map open and after time, returns to the map and attempts to interact with it in a way that requires new tiles (e.g. zoom). The client will need to go through the steps of creating the map again to fix the problem.

-# General Concepts
-
-The following concepts are the same for every endpoint in the API except when it's noted explicitly.
-
-## Auth
-
-By default, users do not have access to private tables in CARTO. In order to instantiate a map from private table data an API Key is required. Additionally, to include some endpoints, an API Key must be included (e.g. creating a Named Map).
-
-To execute an authorized request, `api_key=YOURAPIKEY` should be added to the request URL. The param can be also passed as POST param. Using HTTPS is mandatory when you are performing requests that include your `api_key`.
-
-## Errors
-
-Errors are reported using standard HTTP codes and extended information encoded in JSON with this format:
-
-```javascript
-{
-  "errors": [
-    "access forbidden to table TABLE"
-  ]
-}
-```
-
-If you use JSONP, the 200 HTTP code is always returned so the JavaScript client can receive errors from the JSON object.
-
-## CORS support
-
-All the endpoints, which might be accessed using a web browser, add CORS headers and allow OPTIONS method.

-# Named Maps
-
-Named Maps are essentially the same as Anonymous Maps except the MapConfig is stored on the server, and the map is given a unique name. You can create Named Maps from private data, and users without an API Key can view your Named Map (while keeping your data private).
-
-The Named Map workflow consists of uploading a MapConfig file to CARTO servers, to select data from your CARTO user database by using SQL, and specifying the CartoCSS for your map.
-
-The response back from the API provides the template_id of your Named Map as the `name` (the identifier of your Named Map), which is the name that you specified in the MapConfig. You can  which you can then use to create your Named Map details, or [fetch XYZ tiles](#fetching-xyz-tiles-for-named-maps) directly for Named Maps.
-
-**Tip:** You can also use a Named Map that you created (which is defined by its `name`), to create a map using CARTO.js. This is achieved by adding the [`namedmap` type](http://docs.carto.com/carto-engine/carto-js/layer-source-object/#named-maps-layer-source-object-type-namedmap) layer source object to draw the Named Map.
-
-The main differences, compared to Anonymous Maps, is that Named Maps include:
-
-- **auth token**  
-  This allows you to control who is able to see the map based on an auth token, and create a secure Named Map with password-protection.
-
-- **template map**  
-  The template map is static and may contain placeholders, enabling you to modify your maps appearance by using variables. Templates maps are persistent with no preset expiration. They can only be created, or deleted, by a CARTO user with a valid API KEY (See [auth argument](#arguments)).
-
-  Uploading a MapConfig creates a Named Map. MapConfigs are uploaded to the server by sending the server a "template".json file, which contain the [MapConfig specifications](http://docs.carto.com/carto-engine/maps-api/mapconfig/).
-
-**Note:** There is a limit of 4,096 Named Maps allowed per account. If you need to create more Named Maps, it is recommended to use a single Named Map and change the variables using [placeholders](#placeholder-format), instead of uploading multiple [Named Map MapConfigs](http://docs.carto.com/carto-engine/maps-api/mapconfig/#named-map-layer-options).

-## Create
-
-#### Definition
-
-```html

-
-#### Params
-
-Params | Description
---- | ---
-api_key | is required
-MapConfig | a [Named Map MapConfig](http://docs.carto.com/carto-engine/maps-api/mapconfig/#named-map-layer-options) is required to create a Named Map
-

-  }
-}
-```
-
-#### Arguments
-
-Params | Description
---- | ---
-name | There can only be _one_ template with the same name for any user. Valid names start with a letter or a number, and only contain letters, numbers, dashes (-), or underscores (_). _This is specific to the name of your Named Map that is specified in the `name` property of the template file_.
-
-auth |
---- | ---
-&#124;_ method | `"token"` or `"open"` (`"open"` is the default if no method is specified. Use `"token"` to password-protect your map)
-&#124;_ valid_tokens | when `"method"` is set to `"token"`, the values listed here allow you to instantiate the Named Map. See this [example](http://docs.carto.com/faqs/manipulating-your-data/#how-to-create-a-password-protected-named-map) for how to create a password-protected map.
-placeholders | Placeholders are variables that can be placed in your template.json file's SQL or CartoCSS.
-layergroup | the layergroup configurations, as specified in the template. See [MapConfig File Format](http://docs.carto.com/carto-engine/maps-api/mapconfig/) for more information.
-view (optional) | extra keys to specify the view area for the map. It can be used to have a static preview of a Named Map without having to instantiate it. It is possible to specify it with `center` + `zoom` or with a bounding box `bbox`. Center+zoom takes precedence over bounding box. Also it is possible to choose which layers are visible or not with `preview_layers` indicating its visibility by layer index or id (visible by default).
---- | ---
-&#124;_ zoom | The zoom level to use
-
-&#124;_ center |
---- | ---
-&#124;_ &#124;_ lng | The longitude to use for the center
-&#124;_ &#124;_ lat | The latitude to use for the center
-
-&#124;_ bounds |
---- | ---
-&#124;_ &#124;_ west | LowerCorner longitude for the bounding box, in decimal degrees (aka most western)
-&#124;_ &#124;_ south | LowerCorner latitude for the bounding box, in decimal degrees (aka most southern)
-&#124;_ &#124;_ east | UpperCorner longitude for the bounding box, in decimal degrees (aka most eastern)
-&#124;_ &#124;_ north | UpperCorner latitude for the bounding box, in decimal degrees (aka most northern)
-
-
-### Placeholder Format
-
-Placeholders are variables that can be placed in your template.json file. Placeholders need to be defined with a `type` and a default value for MapConfigs. See details about defining a MapConfig `type` for [Layergoup configurations](http://docs.carto.com/carto-engine/maps-api/mapconfig/#layergroup-configurations).
-
-Valid placeholder names start with a letter and can only contain letters, numbers, or underscores. They have to be written between the `<%=` and `%>` strings in order to be replaced inside the Named Maps API.
-
-#### Example
-
-```javascript
-<%= my_color %>
-```
-
-The set of supported placeholders for a template need to be explicitly defined with a specific type, and default value, for each placeholder.
-
-### Placeholder Types
-
-The placeholder type will determine the kind of escaping for the associated value. Supported types are:
-
-Types | Description
---- | ---
-sql_literal | internal single-quotes will be sql-escaped
-sql_ident | internal double-quotes will be sql-escaped
-number | can only contain numerical representation
-css_color | can only contain color names or hex-values
-
-Placeholder default values will be used whenever new values are not provided as options, at the time of creation on the client. They can also be used to test the template by creating a default version with new options provided.
-
-When using templates, be very careful about your selections as they can give broad access to your data if they are defined loosely.
-
-#### Call
-
-This is the call for creating the Named Map. It is sending the template.json file to the service, and the server responds with the template id.
-
-```bash
-curl -X POST \
-   -H 'Content-Type: application/json' \
-   -d @template.json \
-   'https://{username}.carto.com/api/v1/map/named?api_key={api_key}'
-```
-
-#### Response
-
-The response back from the API provides the name of your MapConfig as a template, enabling you to edit the Named Map details by inserting your variables into the template where placeholders are defined, and create custom queries using SQL.
-
-```javascript
-{
-  "template_id":"name"
-}
-```
-
-## Instantiate
-
-Instantiating a Named Map allows you to fetch the map tiles. You can use the Maps API to instantiate, or use the CARTO.js `createLayer()` function. The result is an Anonymous Map.
-
-#### Definition
-
-```html
-POST /api/v1/map/named/{template_name}
-```
-
-#### Param
-
-Param | Description
---- | ---
-auth_token | `"token"` or `"open"` (`"open"` is the default if not specified. Use `"token"` to password-protect your map)
-
-```javascript
-// params.json, this is required if the Named Map allows variables (if placeholders were defined in the template.json by the user)
-{
- "color": "#ff0000",
- "cartodb_id": 3
-}
-```
-
-The fields you pass as `params.json` depend on the variables allowed by the Named Map. If there are variables missing, it will raise an error (HTTP 400).
-
-**Note:** It is required that you include a `params.json` file to instantiate a Named Map that contains variables, even if you have no fields to pass and the JSON is empty. (This is specific to when a Named Map allows variables (if placeholders were defined in the template.json by the user).
-
-#### Example
-
-You can initialize a template map by passing all of the required parameters in a POST to `/api/v1/map/named/{template_name}`.
-
-Valid auth token will be needed, if required by the template.
-
-
-#### Call
-
-```bash
-curl -X POST \
-  -H 'Content-Type: application/json' \
-  -d @params.json \
-  'https://{username}.carto.com/api/v1/map/named/{template_name}?auth_token={auth_token}'
-```
-
-#### Response
-
-```javascript
-{
-  "layergroupid": "docs@fd2861af@c01a54877c62831bb51720263f91fb33:123456788",
-  "last_updated": "2013-11-14T11:20:15.000Z"
-}
-```
-
-#### Error
-
-```javascript
-{
-  "errors" : ["Some error string here"]
-}
-```
-
-You can then use the `layergroupid` for fetching tiles and grids as you would normally (see [Anonymous Maps](http://docs.carto.com/carto-engine/maps-api/anonymous-maps/)).
-
-## Update
-
-#### Definition
-
-```bash
-PUT /api/v1/map/named/{template_name}
-```
-
-#### Params
-
-Param | Description
---- | ---
-api_key | is required
-
-#### Response
-
-Same as updating a map.
-
-### Other Information
-
-Updating a Named Map removes all the Named Map instances, so they need to be initialized again.
-
-### Example
-
-#### Call
-
-```bash
-curl -X PUT \
-  -H 'Content-Type: application/json' \
-  -d @template.json \
-  'https://{username}.carto.com/api/v1/map/named/{template_name}?api_key={api_key}'
-```
-
-#### Response
-
-```javascript
-{
-  "template_id": "@template_name"
-}
-```
-
-If any template has the same name, it will be updated.
-
-If a template with the same name does NOT exist, a 400 HTTP response is generated with an error in this format:
-
-```javascript
-{
-  "errors" : ["error string here"]
-}
-```
-
-## Delete
-
-Deletes the specified template map from the server, and disables any previously initialized versions of the map.
-
-#### Definition
-
-```bash
-DELETE /api/v1/map/named/{template_name}
-```
-
-#### Params
-
-Param | Description
---- | ---
-api_key | is required
-
-### Example
-
-#### Call
-
-```bash
-curl -X DELETE 'https://{username}.carto.com/api/v1/map/named/{template_name}?api_key={api_key}'
-```
-
-#### Response
-
-```javascript
-{
-  "errors" : ["Some error string here"]
-}
-```
-
-On success, a 204 (No Content) response will be issued. Otherwise a 4xx response with an error will be returned.
-
-## Listing Available Templates
-
-This allows you to get a list of all available templates.
-
-#### Definition
-
-```bash
-GET /api/v1/map/named/
-```
-
-#### Params
-
-Param | Description

-}
-```
-
-#### Error
-

-  "errors" : ["Some error string here"]
-}
-```
-
-## JSONP for Named Maps
-
-If using a [JSONP](https://en.wikipedia.org/wiki/JSONP) (for old browsers) request, there is a special endpoint used to initialize and create a Named Map.
-
-#### Definition
-
-```bash
-GET /api/v1/map/named/{template_name}/jsonp
-```
-
-#### Params
-
-Params | Description
---- | ---
-auth_token | `"token"` or `"open"` (`"open"` is the default if no method is specified. Use `"token"` to password-protect your map)
-params | Encoded JSON with the params (variables) needed for the Named Map
-lmza | You can use an LZMA compressed file instead of a params JSON file
-callback | JSON callback name
-
-#### Call
-
-```bash
-curl 'https://{username}.carto.com/api/v1/map/named/{template_name}/jsonp?auth_token={auth_token}&callback=callback&config=template_params_json'
-```
-
-#### Response
-
-```javascript
-callback({
-  "layergroupid":"c01a54877c62831bb51720263f91fb33:0",
-  "last_updated":"1970-01-01T00:00:00.000Z"
-  "cdn_url": {
-    "http": "http://cdb.com",
-    "https": "https://cdb.com"
-  }
-})
-```
-
-This takes the `callback` function (required), `auth_token` if the template needs auth, and `config` which is the variable for the template (in cases where it has variables).
-
-```javascript
-url += "config=" + encodeURIComponent(
-JSON.stringify({ color: 'red' });
-```
-
-The response is:
-
-```javascript
-callback({
-  layergroupid: "dev@744bd0ed9b047f953fae673d56a47b4d:1390844463021.1401",
-  last_updated: "2014-01-27T17:41:03.021Z"
-})
-```
-
-## CARTO.js for Named Maps
-
-You can use a Named Map that you created (which is defined by its `name`), to create a map using CARTO.js. This is achieved by adding the [`namedmap` type](http://docs.carto.com/carto-engine/carto-js/layer-source-object/#named-maps-layer-source-object-type-namedmap) layer source object to draw the Named Map.
-
-```javascript
-{
-  user_name: '{username}', // Required
-  type: 'namedmap', // Required
-  named_map: {
-    name: '{name_of_map}', // Required, the 'name' of the Named Map that you have created
-    // Optional
-    layers: [{
-      layer_name: "sublayer0", // Optional
-      interactivity: "column1, column2, ..." // Optional
-    },
-    {
-      layer_name: "sublayer1",
-      interactivity: "column1, column2, ..."
-    },
-      ...
-    ],
-    // Optional
-    params: {
-      color: "hex_value",
-      num: 2
-    }
-  }
-}
-```
-
-**Note:** Instantiating a Named Map over a `createLayer` does not require an API Key and by default, does not include auth tokens. _If_ you defined auth tokens for the Named Map configuration, then you will have to include them.
-
-[CARTO.js](http://docs.carto.com/carto-engine/carto-js/) has methods for accessing your Named Maps.
-
-1. [layer.setParams()](http://docs.carto.com/carto-engine/carto-js/api-methods/#layersetparamskey-value) allows you to change the template variables (in the placeholders object) via JavaScript
-
-    **Note:** The CARTO.js `layer.setParams()` function is not supported when using Named Maps for Torque. Alternatively, you can create a [Torque layer in a Named Map](http://bl.ocks.org/iriberri/de37be6406f9cc7cfe5a)
-
-2. [layer.setAuthToken()](http://docs.carto.com/carto-engine/carto-js/api-methods/#layersetauthtokenauthtoken) allows you to set the auth tokens to create the layer
-
-### Torque Layer in a Named Map
-
-If you are creating a Torque layer in a Named Map without using the Torque.js library, you can apply the Torque layer by applying the following code with CARTO.js:
-
-```javascript
- // add cartodb layer with one sublayer
-  cartodb.createLayer(map, {
-    user_name: '{username}',
-    type: 'torque',
-    order: 1,
-    options: {
-            query: "",
-            table_name: "named_map_tutorial_table",
-            user_name: "{username}",
-            tile_style: 'Map { -torque-frame-count:512; -torque-animation-duration:10; -torque-time-attribute:"cartodb_id"; -torque-aggregation-function:"count(cartodb_id)"; -torque-resolution:2; -torque-data-aggregation:linear; } #named_map_tutorial_table_copy{ comp-op: lighter; marker-fill-opacity: 0.9; marker-line-color: #FFF; marker-line-width: 1.5; marker-line-opacity: 1; marker-type: ellipse; marker-width: 6; marker-fill: #FF9900; } #named_map_tutorial_table_copy[frame-offset=1] { marker-width:8; marker-fill-opacity:0.45; } #named_map_tutorial_table_copy[frame-offset=2] { marker-width:10; marker-fill-opacity:0.225; }'      
-
-            },
-    named_map: {
-      name: "{namedmap_example}",
-      layers: [{
-        layer_name: "t"
-       }]
-     }
-    })
-    .addTo(map)
-    .done(function(layer) {
-
-    });
-}

-## Fetching XYZ Tiles for Named Maps
-
-Optionally, authenticated users can fetch projected tiles (XYZ tiles or Mapnik Retina tiles) for your Named Map.
-
-### Fetch XYZ Tiles Directly with a URL
-
-Authenticated users, with an auth token, can use XYZ-based URLs to fetch tiles directly, and instantiate the Named Map as part of the request to your application. You do not have to do any other steps to initialize your map.
-
-To call a template_id in a URL:
-
-`/{template_id}/{layer}/{z}/{x}/{y}.{format}`
-
-For example, a complete URL might appear as:
-
-"https://{username}.carto.com/api/v1/map/named/{template_id}/{layer}/{z}/{x}/{y}.png"
-
-The placeholders indicate the following:
-
-- [`template_id`](http://docs.carto.com/carto-engine/maps-api/named-maps/#response) is the response of your Named Map.
-- layers can be a number (referring to the # layer of your map), all layers of your map, or a list of layers.
-  - To show just the basemap layer, enter the number value `0` in the layer placeholder "https://{username}.carto.com/api/v1/map/named/{template_id}/0/{z}/{x}/{y}.png"
-  - To show the first layer, enter the number value `1` in the layer placeholder "https://{username}.carto.com/api/v1/map/named/{template_id}/1/{z}/{x}/{y}.png"
-  - To show all layers, enter the value `all` for the layer placeholder "https://{username}.carto.com/api/v1/map/named/{template_id}/all/{z}/{x}/{y}.png"
-  - To show a [list of layers](http://docs.carto.com/carto-engine/maps-api/anonymous-maps/#blending-and-layer-selection), enter the comma separated layer value as 0,1,2 in the layer placeholder. For example, to show the basemap and the first layer, "https://{username}.carto.com/api/v1/map/named/{template_id}/0,1/{z}/{x}/{y}.png"
-
-
-### Get Mapnik Retina Tiles
-
-Mapnik Retina tiles are not directly supported for Named Maps, so you cannot use the Named Map template_id. To fetch Mapnik Retina tiles, get the [layergroupid](http://docs.carto.com/carto-engine/maps-api/named-maps/#response-1) to initialize the map.
-
-Instantiate the map by using your `layergroupid` in the token placeholder:
-
- `{token}/{z}/{x}/{y}@{scale_factor}?{x}.{format}`

-# Quickstart
-
-## Anonymous Maps
-
-Here is an example of how to create an Anonymous Map with JavaScript:
-
-```javascript
-var mapconfig = {
-  "version": "1.3.1",
-  "layers": [{
-    "type": "cartodb",
-    "options": {
-      "cartocss_version": "2.1.1",
-      "cartocss": "#layer { polygon-fill: #FFF; }",
-      "sql": "select * from european_countries_e"
-    }
-  }]
-}
-
-$.ajax({
-  crossOrigin: true,
-  type: 'POST',
-  dataType: 'json',
-  contentType: 'application/json',
-  url: 'https://{username}.carto.com/api/v1/map',
-  data: JSON.stringify(mapconfig),
-  success: function(data) {
-    var templateUrl = 'https://{username}.carto.com/api/v1/map/' + data.layergroupid + '/{z}/{x}/{y}.png'
-    console.log(templateUrl);
-  }
-})
-```
-
-## Named Maps
-
-Let's create a Named Map using some private tables in a CARTO account.
-The following map config sets up a map of European countries that have a white fill color:
-
-```javascript
-{
-  "version": "0.0.1",
-  "name": "test",
-  "auth": {
-    "method": "open"
-  },
-  "layergroup": {
-    "layers": [{
-      "type": "mapnik",
-      "options": {
-        "cartocss_version": "2.1.1",
-        "cartocss": "#layer { polygon-fill: #FFF; }",
-        "sql": "select * from european_countries_e"
-      }
-    }]
-  }
-}
-```
-
-The MapConfig needs to be sent to CARTO's Map API using an authenticated call. Here we will use a command line tool called `curl`. For more info about this tool, see [this blog post](http://quickleft.com/blog/command-line-tutorials-curl), or type `man curl` in bash. Using `curl`, and storing the config from above in a file `MapConfig.json`, the call would look like:
-
-#### Call
-
-```bash
-curl 'https://{username}.carto.com/api/v1/map/named?api_key={api_key}' -H 'Content-Type: application/json' -d @mapconfig.json
-```
-
-To get the `URL` to fetch the tiles you need to instantiate the map, where `template_id` is the template name from the previous response.
-
-#### Call
-
-```bash
-curl -X POST 'https://{username}.carto.com/api/v1/map/named/{template_id}' -H 'Content-Type: application/json'
-```
-
-The response will return JSON with properties for the `layergroupid`, the timestamp (`last_updated`) of the last data modification and some key/value pairs with `metadata` for the `layers`.
-
-Note: all `layers` in `metadata` will always have a `type` string and a `meta` dictionary with the key/value pairs.
-
-#### Response
-
-```javascript
-{
-  "layergroupid": "c01a54877c62831bb51720263f91fb33:0",
-  "last_updated": "1970-01-01T00:00:00.000Z",
-  "metadata": {
-    "layers": [
-      {
-        "type": "mapnik",
-        "meta": {}
-      }
-    ]
-  }
-}
-```
-
-You can use the `layergroupid` to instantiate a URL template for accessing tiles on the client. Here we use the `layergroupid` from the example response above in this URL template:
-
-```bash
-https://{username}.carto.com/api/v1/map/{layergroupid}/{z}/{x}/{y}.png
-```

-# Static Maps API
-
-The Static Maps API can be initiated using both Named and Anonymous Maps using the 'layergroupid' token. The API can be used to create static images of parts of maps and thumbnails for use in web design, graphic design, print, field work, and many other applications that require standard image formats.
-
-## Maps API endpoints
-
-Begin by instantiating either a Named or Anonymous Map using the `layergroupid token` as demonstrated in the Maps API documentation above. The `layergroupid` token calls to the map and allows for parameters in the definition to generate static images.
-
-### Zoom + center
-
-#### Definition
-
-```bash
-GET /api/v1/map/static/center/{token}/{z}/{lat}/{lng}/{width}/{height}.{format}
-```
-
-#### Params
-
-Param | Description
---- | ---
-token | the layergroupid token from the map instantiation
-z | the zoom level of the map
-lat | the latitude for the center of the map
-
-format | the format for the image, supported types: `png`, `jpg`
---- | ---
-|_ jpg | will have a default quality of 85.
-
-### Bounding Box
-
-#### Definition
-
-```bash
-GET /api/v1/map/static/bbox/{token}/{bbox}/{width}/{height}.{format}`
-```
-
-#### Params
-
-Param | Description
---- | ---
-token | the layergroupid token from the map instantiation
-
-bbox | the bounding box in WGS 84 (EPSG:4326), comma separated values for:
---- | ---
- | LowerCorner longitude, in decimal degrees (aka most western)
- | LowerCorner latitude, in decimal degrees (aka most southern)
- | UpperCorner longitude, in decimal degrees (aka most eastern)
- | UpperCorner latitude, in decimal degrees (aka most northern)
-width | the width in pixels for the output image
-height | the height in pixels for the output image
-format | the format for the image, supported types: `png`, `jpg`
---- | ---
-|_ jpg | will have a default quality of 85.
-
-Note: you can see this endpoint as
-
-```bash
-GET /api/v1/map/static/bbox/{token}/{west},{south},{east},{north}/{width}/{height}.{format}`
-```
-
-### Named Map
-
-#### Definition
-
-```bash
-GET /api/v1/map/static/named/{name}/{width}/{height}.{format}
-```
-
-#### Params
-
-Param | Description
---- | ---
-name | the name of the Named Map
-width | the width in pixels for the output image
-height | the height in pixels for the output image
-
-format | the format for the image, supported types: `png`, `jpg`
---- | ---
-|_ jpg | will have a default quality of 85.
-
-A Named Maps static image will get its constraints from the [`view` argument of the Create Named Map function](http://docs.carto.com/carto-engine/maps-api/named-maps/#arguments). If `view` is not defined, it will estimate the extent based on the involved tables, otherwise it fallbacks to `"zoom": 1`, `"lng": 0` and `"lat": 0`.
-
-#### Layers
-
-The Static Maps API allows for multiple layers of incorporation into the `MapConfig` to allow for maximum versatility in creating a static map. The examples below were used to generate the static image example in the next section, and appear in the specific order designated.
-
-**Basemaps**
-
-```javascript
-{
-  "type": "http",
-  "options": {
-    "urlTemplate": "http://{s}.basemaps.cartocdn.com/dark_nolabels/{z}/{x}/{y}.png",
-    "subdomains": [
-      "a",
-      "b",
-      "c"
-    ]
-  }
-}
-```
-
-By manipulating the `"urlTemplate"` custom basemaps can be used in generating static images. Supported map types for the Static Maps API are:
-
-```javascript
-'http://{s}.basemaps.cartocdn.com/dark_all/{z}/{x}/{y}.png',
-'http://{s}.basemaps.cartocdn.com/dark_nolabels/{z}/{x}/{y}.png',
-'http://{s}.basemaps.cartocdn.com/light_all/{z}/{x}/{y}.png',
-'http://{s}.basemaps.cartocdn.com/light_nolabels/{z}/{x}/{y}.png',
-```
-
-**Mapnik**
-
-```javascript
-{
-  "type": "mapnik",
-  "options": {
-    "sql": "select null::geometry the_geom_webmercator",
-    "cartocss": "#layer {\n\tpolygon-fill: #FF3300;\n\tpolygon-opacity: 0;\n\tline-color: #333;\n\tline-width: 0;\n\tline-opacity: 0;\n}",
-    "cartocss_version": "2.2.0"
-  }
-},
-```
-
-**CARTO**
-
-As described in the [MapConfig File Format](http://docs.carto.com/carto-engine/maps-api/mapconfig/), a "cartodb" type layer is now just an alias to a "mapnik" type layer as above, intended for backwards compatibility.
-
-```javascript
-{
-  "type": "cartodb",
-  "options": {
-    "sql": "select * from park",
-    "cartocss": "/** simple visualization */\n\n#park{\n  polygon-fill: #229A00;\n  polygon-opacity: 0.7;\n  line-color: #FFF;\n  line-width: 0;\n  line-opacity: 1;\n}",
-    "cartocss_version": "2.1.1"
-  }
-}
-```
-
-Additionally, static images from Torque maps and other map layers can be used together to generate highly customizable and versatile static maps.
-
-
-### Caching
-
-It is important to note that generated images are cached from the live data referenced with the `layergroupid token` on the specified CARTO account. This means that if the data changes, the cached image will also change. When linking dynamically, it is important to take into consideration the state of the data and longevity of the static image to avoid broken images or changes in how the image is displayed. To obtain a static snapshot of the map as it is today and preserve the image long-term regardless of changes in data, the image must be saved and stored locally.
-
-### Limits
-
-* While images can encompass an entirety of a map, the default limit for pixel range is 8192 x 8192.
-* Image resolution by default is set to 72 DPI
-* JPEG quality by default is 85%
-* Timeout limits for generating static maps are the same across CARTO Builder and CARTO Engine. It is important to ensure timely processing of queries.
-
-## Examples
-
-After instantiating a map from a CARTO account:
-
-#### Call
-
-```bash
- GET /api/v1/map/static/center/{layergroupid}/{z}/{x}/{y}/{width}/{height}.png
-```
-
-#### Response
-
-<p class="wrap-border"><img src="https://raw.githubusercontent.com/namessanti/Pictures/master/static_api.png" alt="static-api"/></p>
-
-### MapConfig
-
-For this map, the multiple layers, order, and stylings are defined by the MapConfig.
-
-```javascript
-{
-  "version": "1.3.0",
-  "layers": [
-    {
-      "type": "http",
