The bearer token is provided as a value of the “Authorization” header parameter using the “Bearer” authentication scheme:
Authorization: Bearer <token>
or alternatively, as a URI query parameter:
To obtain the credentials for an application, visit http://developer.here.com/plans to register with HERE.
