 ## CartoDB.js for Named Maps

 You can use a Named Map that you created (which is defined by its `name`), to create a map using CartoDB.js. This is achieved by adding the [`namedmap` type](http://docs.cartodb.com/cartodb-platform/cartodb-js/layer-source-object/#named-maps-layer-source-object-type-namedmap) layer source object to draw the Named Map.

 **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.
 
 [CartoDB.js](http://docs.cartodb.com/cartodb-platform/cartodb-js/) has methods for accessing your Named Maps.
 
 1. [layer.setParams()](http://docs.cartodb.com/cartodb-platform/cartodb-js/api-methods/#layersetparamskey-value) allows you to change the template variables (in the placeholders object) via JavaScript
