Empower OAuth 2.0 API

aid: great-west-lifeco:empower-oauth-2-0-api
name: Empower OAuth 2.0 API
description: The authorization API for Empower's API suite, listed as "production" in the public Empower
  developer portal catalog. It generates bearer access tokens used to authorize calls to the other Empower
  APIs. Public release notes on the catalog page document /auth and /token endpoints, an optional x-api-key
  header on both, and an invalid_grant 400 response when a requested OAuth scope is not configured on
  the client profile. Empower documents OAuth 2.0 and OpenID Connect with the client_credentials grant
  for B2B partner integration, and is moving to asymmetric private-key JWT client authentication (PKI)
  in line with Financial-grade API (FAPI) practice. Reference documentation is behind login and the authorization
  service endpoint is communicated privately to approved partners. The baseURL below is the probe-observed
  U.S. API gateway host; the authorization service host itself is never published.
