Venue Maps API Developer's Guide

Signed Requests

Unlike other HERE APIs, the Venue Maps API requires you to sign your requests. This extra requirement provides more efficient performance and extra security:
  • It prevents unauthorized users from using your access credentials.
  • It also reduces the number internal transactions that are required to authenticate your requests.

You sign your request with the signature, policy, and Key-pair-ID parameters. You can request values for these parameters from the signature service. These signature parameters are valid for 24 hours. After 24 hours, you must request new signature parameters.

Before you request the signature parameters, make sure you've received the standard access and authorization credentials first.
