The credentials are of two types:
- HERE application credentials – application-specific ID and code (
- Data Lens access token – based on the
app_code, needed to invoke operations supported by Data Lens, but not needed to access published query data
Note that the application credentials are issued for the lifetime of an application registered with HERE. By contrast an access token remains valid for 60 minutes. The Data Lens REST API provides facilities to refresh and cancel the token, as required.
For details of how to obtain credentials and how to use them, see Authentication.
