What is the OAuth2 callback URL for an ASP.Net Core Application
When I setup an ASP.Net Core MVC application, and add in the AspNetCore Authentication libraries, it handles the handshakes for OAuth 2 and OIDC's Code Authentication Flow.
However, I need to configure my Identity Provider with the callback URL to send the code to my application.
Assuming my Application is hosted at https://example.com/myapp/home what would be the callback URL that I should say my application is expecting the IDP to call?
Solution
The default callback URL for AddOpenIdConnect in ASP.NET core is
/signin-oidc
In your case (Depending on your configuration) it could be:
https://example.com/signin-oidc
You can if necessary, customize the URL that the handler is looking for using the CallbackPath property.
