You don't have to evaluate OAuth/OIDC request parameters sent from API clients. Forward them right away to Authlete so that it can do protocol handling and token management on your OAuth/OIDC server's behalf and tell you what to do next.
Authlete provides a set of intuitive backend APIs carefully crafted to focus on the core of OAuth/OIDC. You can develop your OAuth/OIDC server frontend with your preferred programming languages and frameworks, and integrate it with identity and access management services as well as API gateways.
We are committed to open standards such as OAuth, OpenID Connect, JWT, UK Open Banking, CIBA. Authlete is not only OpenID Connect certified but also the first Financial-grade API (FAPI) certified solution for production environment.
