Our backend datasource I have unauthenticated GET methods working, but now am working on some POSTs and am running into an issue with putting "Authorization: Bearer token_value" in the header. If the call is successful, the response for the POST request contains a JSON string that includes several properties, including access_token, token_type, and refresh_token (if you requested the wl.offline_access scope). It also holds information about the user unless the web app accepts service-to-service calls from a daemon app. The following are example steps using Azure AD as the OAuth 2.0 provider. It uses the same TokenValidationParameters class to specify the validation options: If your authorization server publishes a metadata document, you can retrieve it with the OpenIdConnectConfigurationRetriever class in the Microsoft.IdentityModel.Protocols.OpenIdConnect package.
