I’ve been using Postman with OAuth 2.0 for a few months after following the instructions in this excellent post: Microsoft identity platform and Microsoft Entra ID with ASP.NET Core | Microsoft Learn.
This weekend it stopped working. After taking the client credentials, I’m routed to the callback URL: Postman. In the past, this has been enough to tell Postman to continue on with issuing the authentication token, but now I just get some promotional stuff from Postman.
Anyone know what’s going on or whether I’m using the proper reply URL?
