Using OAuth2 OBO with Azure AD B2C

Developer Support

In this post, Consultant Marius Rochon gives an implementation of OAuth2 Extension Grants (OBO) using Azure AD B2C.

Currently, Azure B2C does not support the extension grant. This sample uses a custom web service (B2BOBOWeb) to provide a token endpoint, which handles the Extension Grant requests and communicates with B2C to respond with a valid response (access token). It uses a specific B2C tenant configured with custom journeys to handle this communication.

Note: this sample code, not intended for production use.
