api_key

If the APIs contents are less sensitive we simply require an HTTP header to identify the caller. To successfully invoke the API, then, you just need to populate the X-Api-Key header with the key assigned to your Application. You should have received this key via e-mail. Refer to the _**Register your Application**_ section for instructions on how to get a key. ## API Console Click on the _**Authorize**_ button.  Fill the required field with your key and then click on the _**Authorize**_ button.  Now just click on _Close_.  The key is now been set and will, until you navigate away from this page, automatically be included in every call that you make to the API.
