Cross-Domain JavaScript Requests

Often, browsers prevent access to certain servers due to security restrictions. Cross-Domain Javscript Requests allow developers to work around security restrictions that would prevent an application from contacting EV Charging Stations API directly. For example, certain location information might not be retrievable without enabling this method. In order to allow full accees to servers, the EV Charging Stations API provides a mechanism to enable client-side cross-origin requests that allow JavaScript resources to be fetched from another domain.

For details on how this mechanism operates, see Cross-Origin Resource Sharing. EV Charging Stations API currently uses all headers and parameters of this mechanism.

In order to support browser platforms which do not yet implement Cross-Origin Resource Sharing, GET requests can alternatively be made using JSONP. To use JSONP, your application simply supplies the name of its callback function in the jsoncallback or jsonpCallback query string parameter.

For example, to use JSONP to search EV stations with a callback named myCallbackFunction, you could make a request using a bearer token like the example below:

GET https://ev-v2.cc.api.here.com/ev/stations.json
?prox=52.516667,13.383333,5000
&jsoncallback=myCallbackFunction
-H "Authorization: Bearer{YOUR_TOKEN}'
  

Using an API Key

GET
https://ev-v2.cc.api.here.com/ev/stations.json
?prox=52.516667,13.383333,5000
&jsoncallback=myCallbackFunction&apiKey={YOUR_API_KEY};
       
Note: The JSONP mechanism only works for GET requests. POST requests can only be made using the Cross-Origin Resource Sharing mechanism discussed above.
