+1.26.0 -- 2015-01-27
+--------------------
+
+Announcements:
+ - Upgrades windshaft to 0.35.0, supports mapconfig version `1.3.0`
+
+
+1.25.0 -- 2015-01-26
+--------------------
+
+Announcements:
+ - No more signed maps (#227 and #238)
+    - Splits template maps endpoint into its own controller
+    - Removes TemplateMaps dependency on SignedMaps
+     - Token validation is done against the template
+     - Template is always extended with default values for auth and placeholders
+     - MapConfig is extended, in order to validate auth_tokens, with template info:
+        - template name
+        - template auth
+     - No more locks to create, update or delete templates
+        - Trusting in redis' hash semantics
+        - Some tradeoffs:
+            * A client having more templates than allowed by a race condition between limit (HLEN) check and creation (HSET)
+            * Updating a template could happen while deleting it, resulting in a new template
+            * Templates already instantiated will be accessible through their layergroup so it is possible to continue requesting tiles/grids/etc.
+     - Authorisation is now handled by template maps
+    - Template instantiation returns new instances with default values if they are missing
+
+
+New features:
+ - Basic layergroup validation on named map creation/update (#196)
+ - Add named maps surrogate keys and call invalidation on template modification/deletion (#247)
+    - Extends TemplateMaps backend with EventEmitter
+        - Emits for create, update and delete templates
+    - VarnishHttpCacheBackend will invalidate a varnish instance via HTTP PURGE method
+        - In the future there could be more backends, for instance to invalidate a CDN.
+    - NamedMapsEntry has the responibility to generate a cache key for a named map
+        - It probably should receive a template/named map instead of owner and template name
+    - SurrogateKeysCache is resposible to tag responses with a header
+        - It also is responsible for invalidations given an Invalidation Backend
+        - In the future it could have several backends so it can invalidates different caches
+    - SurrogateKeysCache is subscribed to TemplateMaps events to do the invalidations

+# Kind of maps
+
+Windshaft-CartoDB supports the following types of maps:
+
+ - [Temporary maps](#temporary-maps) (created by anyone)
+   - [Detached maps](#detached-maps)
+   - [Inline maps](#inline-maps) (legacy)
+ - [Persistent maps](#peristent-maps) (created by CartDB user)
+   - [Template maps](#template-maps)
+   - [Table maps](#table-maps) (legacy, deprecated) 
+
+## Temporary maps
+
+Temporary maps have no owners and are anonymous in nature.
+There are two kinds of temporary maps:
+
+ - Detached maps (aka MultiLayer-API)
+ - Inline maps 
+
+### Detached maps
+
+Detached maps are maps that are configured with a request
+obtaining a temporary token and then used by referencing
+the obtained token. The token expires automatically when unused.
+
+Anyone can create detached maps, but users will need read access
+to the data source of the map layers.
+
+The configuration format is a [MapConfig]
+(http://github.com/CartoDB/Windshaft/wiki/MapConfig-specification) document.
+
+The HTTP endpoints for creating the map and using it are described [here]
+(http://github.com/CartoDB/Windshaft-cartodb/wiki/MultiLayer-API)
+
+*TODO* cleanup the referenced document
+
+### Inline maps
+
+Inline maps are maps that only exist for a single request,
+being the request for a specific map resource (tile).
+
+Inline maps are always bound to a table, and can only be
+obtained by those having read access to the that table.
+Additionally, users need to have access to any datasource
+specified as part of the configuration.
+
+Inline maps only support PNG and UTF8GRID tiles.
+
+The configuration consist in a set of parameters, to be
+specified in the query string of the tile request:
+
+ * sql - the query to run as datasource, can be an array
+ * style - the CartoCSS style for the datasource, can be an array
+ * style_version - version of the CartoCSS style, can be an array
+ * interactivity - only for fetching UTF8GRID, 
+
+If the style is not provided, style of the associated table is
+used; if the sql is not provided, all records of the associated
+table are used as the datasource; the two possibilities result
+in a mix between _inline_ maps and [Table maps][].
+
+*TODO* specify (or link) api endpoints
+
+## Persistent maps
+
+Persistent maps can only be created by a CartoDB user who has full
+responsibility over editing and deleting them. There are two
+kind of persistent maps:
+
+ - Template maps 
+ - Table maps (legacy, deprecated) 
+
+### Templated maps
+
+Templated maps are templated [MapConfig]
+(http://github.com/CartoDB/Windshaft/wiki/MapConfig-specification) documents
+associated with an authorization certificate.
+
+The authorization certificate determines who can instanciate the
+template and use the resulting map. Authorized users of the instanciated
+maps will have the same database access privilege of the template owner.
+
+The HTTP endpoints for creating and using templated maps are described [here]
+(http://github.com/CartoDB/Windshaft-cartodb/wiki/Template-maps).
+
+*TODO* cleanup the referenced document
+
+### Table maps
+
+Table maps are maps associated with a table.
+Configuration of such maps is limited to the CartoCSS style.
+
+ * style - the CartoCSS style for the datasource, can be an array
+ * style_version - version of the CartoCSS style, can be an array
+
+You can only fetch PNG or UTF8GRID tiles from these maps.
+
+Access method is the same as the one for [Inline maps](#inline-maps)

-# Kind of maps
+## Maps API
 
-Windshaft-CartoDB supports these kind of maps:
+The CartoDB Maps API allows you to generate maps based on data hosted in your CartoDB account, and you can 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/).
 
- - [Temporary maps](#temporary-maps) (created by anyone)
-   - [Detached maps](#detached-maps)
-   - [Inline maps](#inline-maps) (legacy)
- - [Persistent maps](#peristent-maps) (created by CartDB user)
-   - [Template maps](#template-maps)
-   - [Table maps](#table-maps) (legacy, deprecated) 
+You can create two types of maps with the Maps API:
 
-## Temporary maps
+- **Anonymous maps**  
+  Maps that can be created using your CartoDB 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 CartoDB.js example]({{ '/cartodb-platform/cartodb-js.html' | prepend: site.baseurl }}).
 
-Temporary maps have no owners and are anonymous in nature.
-There are two kind of temporary maps:
+- **Named maps**  
+  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. 
 
- - Detached maps (aka MultiLayer-API)
- - Inline maps 
+## Quickstart
 
-### Detached maps
+### Anonymous maps
 
-Detached maps are maps which are configured with a request
-obtaining a temporary token and then used by referencing
-the obtained token. The token expires automatically when unused.
+Here is an example of how to create an anonymous map with JavaScript:
 
-Anyone can create detached maps, but users will need read access
-to the data source of the map layers.
+```javascript
+var mapconfig = {
+  "version": "1.0.1",
+  "layers": [{
+    "type": "cartodb",
+    "options": {
+      "cartocss_version": "2.1.1",
+      "cartocss": "#layer { polygon-fill: #FFF; }",
+      "sql": "select * from european_countries_e"
+    }
+  }]
+}
 
-The configuration format is a [MapConfig]
-(http://github.com/CartoDB/Windshaft/wiki/MapConfig-specification) document.
+$.ajax({
+  crossOrigin: true,
+  type: 'POST',
+  dataType: 'json',
+  contentType: 'application/json',
+  url: 'http://documentation.cartodb.com/api/v1/map',
+  data: JSON.stringify(mapconfig),
+  success: function(data) {
+    var templateUrl = 'http://documentation.cartodb.com/api/v1/map/' + data.layergroupid + '/{z}/{x}/{y}.png'

+  }
+})
+```

-Inline maps are maps that only exist for a single request,
-being the request for a specific map resource (tile).
+The map config needs to be sent to CartoDB'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:
 
-Inline maps are always bound to a table, and can only be
-obtained by those having read access to the that table.
-Additionally, users need to have access to any datasource
-specified as part of the configuration.
+<div class="code-title notitle code-request"></div>
+```bash
+curl 'https://{account}.cartodb.com/api/v1/map/named?api_key=APIKEY' -H 'Content-Type: application/json' -d @mapconfig.json
+```
 
-Inline maps only support PNG and UTF8GRID tiles.
+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.
 
-The configuration consist in a set of parameters, to be
-specified in the query string of the tile request:
+<div class="code-title notitle code-request"></div>
+```bash
+curl -X POST 'http://{account}.cartodb.com/api/v1/map/named/:template_id' -H 'Content-Type: application/json'
+```
 
- * sql - the query to run as datasource, can be an array
- * style - the CartoCSS style for the datasource, can be an array
- * style_version - version of the CartoCSS style, can be an array
- * interactivity - only for fetching UTF8GRID, 
+The response will return JSON with properties for the `layergroupid`, `cdn_url`, and the timestamp (`last_updated`) of the last data modification. 
 
-If the style is not provided, style of the associated table is
-used; if the sql is not provided, all records of the associated
-table are used as the datasource; the two possibilities result
-in a mix between _inline_ maps and [Table maps][].
+Here is an example response:
 
-*TODO* specify (or link) api endpoints
+```javascript
+{
+  "cdn_url": {
+    "http": "ashbu.cartocdn.com",
+    "https": "cartocdn-ashbu.global.ssl.fastly.net"
+  },
+  "layergroupid": "c01a54877c62831bb51720263f91fb33:0",
+  "last_updated": "1970-01-01T00:00:00.000Z"
+}
+```
 
-## Persistent maps
+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:
 
-Persistent maps can only be created by a CartoDB user who has full
-responsibility over editing and deleting them. There are two
-kind of persistent maps:
+```bash
+http://documentation.cartodb.com/api/v1/map/c01a54877c62831bb51720263f91fb33:0/{z}/{x}/{y}.png
+```
 
- - Template maps 
- - Table maps (legacy, deprecated) 
+## General Concepts
 
-### Templated maps
+The following concepts are the same for every endpoint in the API except when it's noted explicitly.
 
-Templated maps are templated [MapConfig]
-(http://github.com/CartoDB/Windshaft/wiki/MapConfig-specification) documents
-associated with an authorization certificate.
+### Auth
 
-The authorization certificate determines who can instanciate the
-template and use the resulting map. Authorized users of the instanciated
-maps will have the same database access privilege of the template owner.
+By default, users do not have access to private tables in CartoDB. 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).
 
-The HTTP endpoints for creating and using templated maps are described [here]
-(http://github.com/CartoDB/Windshaft-cartodb/wiki/Template-maps).
+To execute an authorized request, api_key=YOURAPIKEY should be added to the request URL. The param can be also passed as POST param. We **strongly advise** using HTTPS when you are performing requests that include your `api_key`.
 
-*TODO* cleanup the referenced document
+### Errors
 
-### Table maps
+Errors are reported using standard HTTP codes and extended information encoded in JSON with this format:
 
-Table maps are maps associated with a table.
-Configuration of such maps is limited to the CartoCSS style.
+```javascript
+{
+  "errors": [
+    "access forbidden to table TABLE"
+  ]
+}
+```
 
- * style - the CartoCSS style for the datasource, can be an array
- * style_version - version of the CartoCSS style, can be an array
+If you use JSONP, the 200 HTTP code is always returned so the JavaScript client can receive errors from the JSON object.
 
-You can only fetch PNG or UTF8GRID tiles from these maps.
+### CORS support
 
-Access method is the same as the one for [Inline maps](#inline-maps)
+All the endpoints which might be accessed using a web browser add CORS headers and allow OPTIONS method.

+Anonymous maps allows you to instantiate a map given SQL and CartoCSS. It also allows you to add interaction capabilities using [UTF Grid.](https://github.com/mapbox/utfgrid-spec)
+
+### Instantiate
+
+#### Definition
+
+<div class="code-title notitle code-request"></div>
+```html
+POST /api/v1/map
+```
+
+#### Params
+
+```javascript
+{
+  "version": "1.0.1",
+  "layers": [{
+    "type": "cartodb",
+    "options": {
+      "cartocss_version": "2.1.1",

+      "sql": "select * from european_countries_e",
+      "interactivity": ["cartodb_id", "iso3"]
+    }
+  }]
+}
+```
+
+Should be a [Mapconfig](https://github.com/CartoDB/Windshaft/blob/0.19.1/doc/MapConfig-1.1.0.md).
+
+#### Response
+
+The response includes:
+
+- **layergroupid**  
+  The ID for that map, used to compose the URL for the tiles. The final URL is:
+
+  ```html
+  http://{account}.cartodb.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** *(optional)*  
+  Includes information about the layers. Some layers may not have metadata.
+
+- **cdn_url**  
+  URLs to fetch the data using the best CDN for your zone.
+
+#### Example
+
+<div class="code-title code-request with-result">REQUEST</div>
+```bash
+curl 'http://documentation.cartodb.com/api/v1/map' -H 'Content-Type: application/json' -d @mapconfig.json
+```
+
+<div class="code-title">RESPONSE</div>
+```javascript
+{
+  "layergroupid":"c01a54877c62831bb51720263f91fb33:0",
+  "last_updated":"1970-01-01T00:00:00.000Z"
+  "cdn_url": {
+    "http": "http://cdb.com",
+    "https": "https://cdb.com"
+  }
+}
+```
+
+The tiles can be accessed using:
+
+```bash
+http://documentation.cartodb.com/api/v1/map/c01a54877c62831bb51720263f91fb33:0/{z}/{x}/{y}.png
+```
+
+For UTF grid tiles:
+
+```bash
+http://documentation.cartodb.com/api/v1/map/c01a54877c62831bb51720263f91fb33:0/:layer/{z}/{x}/{y}.grid.json
+```
+
+For attributes defined in `attributes` section:
+
+```bash
+http://documentation.cartodb.com/api/v1/map/c01a54877c62831bb51720263f91fb33:0/:layer/attributes/:feature_id
+```
+
+Which returns JSON with the attributes defined, like:
+
+```javascript
+{ c: 1, d: 2 }
+```
+
+Notice UTF Grid and attributes endpoints need an integer parameter, ``layer``. That number is the 0-based index of the layer inside the mapconfig. So in this case 0 returns the UTF grid tiles/attributes for layer 0, the only layer in the example mapconfig. If a second layer was available it could be returned with 1, a third layer with 2, etc.
+
+### Create JSONP
+
+The JSONP endpoint is provided in order to allow web browsers access which don't support CORS.
+
+#### Definition
+
+<div class="code-title notitle code-request"></div>
+```bash
+GET /api/v1/map?callback=method
+```
+
+#### Params
+
+- **config**
+  Encoded JSON with the params for creating named maps (the variables defined in the template).
+
+- **lmza**  
+  This attribute contains the same as config but LZMA compressed. It cannot be used at the same time as `config`.
+
+- **callback**  
+  JSON callback name.
+
+#### Example
+
+<div class="code-title code-request with-result">REQUEST</div>
+```bash
+curl "https://documentation.cartodb.com/api/v1/map?callback=callback&config=%7B%22version%22%3A%221.0.1%22%2C%22layers%22%3A%5B%7B%22type%22%3A%22cartodb%22%2C%22options%22%3A%7B%22sql%22%3A%22select+%2A+from+european_countries_e%22%2C%22cartocss%22%3A%22%23european_countries_e%7B+polygon-fill%3A+%23FF6600%3B+%7D%22%2C%22cartocss_version%22%3A%222.3.0%22%2C%22interactivity%22%3A%5B%22cartodb_id%22%5D%7D%7D%5D%7D"

+        "https": "https://cdb.com"
+    },
+    last_updated: "1970-01-01T00:00:00.000Z"
+})
+```
+
+### Remove
+
+Anonymous maps cannot be removed by an API call. They will expire after about five minutes but 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 an 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.
 
 
-NOTE: in case Multilayer-API does not contain this info yet, the
-      endpoint for fetching attributes is this:
+## Named Maps
 
-- **/api/maps/:map_id/:layer_index/attributes/:feature_id** 
-   - would return { c: 1, d: 2 }
+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. Two other big differences are that you can create named maps from private data, and that users without an API Key can see them even though they are from that private data.
 
+The main two differences compared to anonymous maps are:
+
+- **auth layer**  
+  This allows you to control who is able to see the map based on a token auth
+
+- **templates**  
+  Since the mapconfig is static it can contain some variables so the client can modify the map's appearance using those variables
+
+Template maps are persistent with no preset expiration. They can only be created or deleted by a CartoDB user with a valid API_KEY (see [auth section](http://docs.cartodb.com/cartodb-platform/maps-api.html#auth)).
+
+### Create
+
+#### Definition
+
+<div class="code-title notitle code-request"></div>
+```html
+POST /api/v1/map/named
+```
+
+#### Params
+
+- **api_key** is required
+
+<div class="code-title">template.json</div>
+```javascript
+{
+  "version": "0.0.1",
+  "name": "template_name",
+  "auth": {
+    "method": "token",
+    "valid_tokens": [
+      "auth_token1",
+      "auth_token2"
+    ]
+  },
+  "placeholders": {
+    "color": {
+      "type": "css_color",
+      "default": "red"
+    },
+    "cartodb_id": {
+      "type": "number",
+      "default": 1
+    }
+  },
+  "layergroup": {
+    "version": "1.0.1",
+    "layers": [
+      {
+        "type": "cartodb",
+        "options": {
+          "cartocss_version": "2.1.1",
+          "cartocss": "#layer { polygon-fill: <%= color %>; }",
+          "sql": "select * from european_countries_e WHERE cartodb_id = <%= cartodb_id %>"
+        }
+      }
+    ]
+  }
+}
+```
+
+##### Arguments
+
+- **name**: There can be at most _one_ template with the same name for any user. Valid names start with a letter, and only contain letters, numbers, or underscores (_).
+- **auth**:
+  - **method** `"token"` or `"open"` (the default if no `"method"` is given).
+  - **valid_tokens** when `"method"` is set to `"token"`, the values listed here allow you to instantiate the named map.
+- **placeholders**: Variables not listed here are not substituted. Variable not provided at instantiation time trigger an error. A default is required for optional variables. Type specification is used for quoting, to avoid injections see template format section below.
+- **layergroup**: the layer list definition. This is the MapConfig explained in anonymous maps. See [MapConfig documentation](https://github.com/CartoDB/Windshaft/blob/master/doc/MapConfig-1.1.0.md) for more info.
+
+#### Template Format
+
+A templated `layergroup` allows the use of placeholders in the "cartocss" and "sql" elements of the "option" object in any "layer" of a `layergroup` configuration
+
+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.
+
+##### Example
+
+```javascript
+<%= my_color %>
+```
+
+The set of supported placeholders for a template will need to be explicitly defined with a specific type and default value for each.
+
+#### Placeholder Types
+
+The placeholder type will determine the kind of escaping for the associated value. Supported types are:
+
+- **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 now options provided.
+
+When using templates, be very careful about your selections as they can give broad access to your data if they are defined losely.
+
+<div class="code-title code-request with-result">REQUEST</div>

+
+<div class="code-title">RESPONSE</div>
+```javascript

+
+### Instantiate
+
+Instantiating a map allows you to get the information needed to fetch tiles. That temporal map is an anonymous map.
+
+#### Definition
+
+<div class="code-title notitle code-request"></div>
+```html
+POST /api/v1/map/named/:template_name
+```
+
+#### Param
+
+- **auth_token** optional, but required when `"method"` is set to `"token"`
+
+```javascript
+// params.json
+{
+ "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).
+
+- **auth_token** *optional* if the named map needs auth
+
+#### 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 credentials will be needed if required by the template.
+
+<div class="code-title code-request with-result">REQUEST</div>
+```bash
+curl -X POST \
+  -H 'Content-Type: application/json' \
+  -d @params.json \
+  'https://documentation.cartodb.com/api/v1/map/named/@template_name?auth_token=AUTH_TOKEN'
+```
+
+<div class="code-title">Response</div>
+```javascript
+{
+  "layergroupid": "docs@fd2861af@c01a54877c62831bb51720263f91fb33:123456788",
+  "last_updated": "2013-11-14T11:20:15.000Z"
+}
+```
+
+<div class="code-title">Error</div>
+```javascript
+{
+  "error": "Some error string here"
+}
+```
+
+You can then use the `layergroupid` for fetching tiles and grids as you would normally (see anonymous map section).  However, you'll need to show the `auth_token`, if required by the template.
+
+### Using JSONP
+
+There is also a special endpoint to be able to initialize a map using JSONP (for old browsers).
+
+#### Definition
+
+<div class="code-title notitle code-request"></div>
+```bash
+GET /api/v1/map/named/:template_name/jsonp
+```
+
+#### Params
+
+- **auth_token** optional, but required when `"method"` is set to `"token"`
+- **config** Encoded JSON with the params for creating named maps (the variables defined in the template)
+- **lmza** This attribute contains the same as config but LZMA compressed. It cannot be used at the same time than `config`.
+- **callback:** JSON callback name
+
+<div class="code-title code-request with-result">REQUEST</div>
+```bash
+curl 'https://documentation.cartodb.com/api/v1/map/named/:template_name/jsonp?auth_token=AUTH_TOKEN&callback=callback&config=template_params_json'
+```
+
+<div class="code-title">RESPONSE</div>
+```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 in this format:
+
+```javascript
+callback({
+  layergroupid: "dev@744bd0ed9b047f953fae673d56a47b4d:1390844463021.1401",
+  last_updated: "2014-01-27T17:41:03.021Z"
+})
+```
+
+### Update
+
+#### Definition
+
+<div class="code-title notitle code-request"></div>
+```bash
+PUT /api/v1/map/named/:template_name
+```
+
+#### Params
+
+- **api_key** is required
+
+#### Response
+
+Same as updating a map.
+
+#### Other Info
+
+Updating a named map removes all the named map instances so they need to be initialized again.
+
+#### Example
+
+<div class="code-title code-request with-result">REQUEST</div>
+```bash
+curl -X PUT \
+  -H 'Content-Type: application/json' \

+```
+
+<div class="code-title">RESPONSE</div>
+```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
+{
+  "error": "error string here"
+}
+```
+
+### Delete 
+
+Delete the specified template map from the server and disables any previously initialized versions of the map.

+
+<div class="code-title">RESPONSE</div>
+```javascript
+{
+  "error": "Some error string here"

+
+### Use with CartoDB.js
+Named maps can be used with CartoDB.js by specifying a named map in a layer source as follows. Named maps are treated almost the same as other layer source types in most other ways.
+
+```js
+var layerSource = {
+  user_name: '{your_user_name}', 
+  type: 'namedmap', 
+  named_map: { 
+    name: '{template_name}', 
+	layers: [{ 
+	  layer_name: "layer1", 
+      interactivity: "column1, column2, ..." 
+	}] 
+  } 
+}
+
+cartodb.createLayer('map_dom_id',layerSource)
+  .addTo(map_object);
+
+```
+
+See [CartoDB.js](http://docs.cartodb.com/cartodb-platform/cartodb-js.html) methods [layer.setParams()](http://docs.cartodb.com/cartodb-platform/cartodb-js.html#layersetparamskey-value) and [layer.setAuthToken()](http://docs.cartodb.com/cartodb-platform/cartodb-js.html#layersetauthtokenauthtoken).
