Empower OAuth 2.0 API is one of 3 APIs that [Great-West Lifeco](https://apis.io/providers/great-west-lifeco/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Authentication, Authorization, Security, OpenID Connect, and Login Gated. The published artifact set on APIs.io includes API documentation, authentication docs, and a changelog.

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.
