Authentication and Authorization API Developer's Guide

Creating a Signature

The HERE Authentication and Authorization API requires that you sign your requests using the signing process described in the OAuth Core 1.0 specification. Use either the AAA Java SDK or any third-party library that conforms to the OAuth 1.0 specification with “HMAC-SHA256” as the signature method.

Note: You must create a new signature for each token request to the Authentication and Authorization API. Signatures can only be used once.
