        note: >-
          Live token endpoint returns RFC 6749 errors (POST with no
          credentials -> HTTP 400 {"error":"invalid_client"}), confirming an
          OAuth2 client-authenticated token endpoint. Client credentials are
          issued through the gated rewardStyle Developer Portal
          (registration at https://api.rewardstyle.com/register).

notes: >-
  The rewardStyle Developer Portal (api.rewardstyle.com) is registration-gated;
  the full API reference, OpenAPI/Swagger spec, and scope list are only visible
  to approved partners after login, so scopes could not be enumerated publicly.
  The public, verifiable surface is the OAuth2 token endpoint behavior above.
