I’ve been using Postman with OAuth 2.0 for a few months after following the instructions in this excellent post: https://docs.microsoft.com/en-us/aspnet/core/security/authentication/azure-ad-b2c-webapi?view=aspnetcore-2.2.
This weekend it stopped working. After taking the client credentials, I’m routed to the callback URL: https://getpostman.com/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?
