What are ADP Client Connection Libraries?

ADP Client Connection Library supports OAuth2 Authorization Code and Client Credentials flows. ID token retrieval via OpenID Connect based Authorization Code flow is also supported. The following table shows the availability of the library for various languages. As of June 2022, ADP no longer provides support for code libraries for various programming languages.
