Getting Redirect URI Mismatch error in Azure AD b2C

New in Azure AD B2C, and need your help. I am getting a redirect URI mismatch error while trying to use the Run User Flow option in Azure Portal. I have verified the redirect URL configured in the app. Please refer to the screenshots below. enter image description here

Please let me know what am I doing wrong here

Solution

  • Yes, I agree with @juunas. The redirect URI changes might take a few minutes to propagate across Azure AD B2C.

    I have one app registration with redirect URI configured as https://jwt.ms in Web platform as below:

    enter image description here

    I created one user flow named B2C_1_signupsignin and selected above app registration before running it:

    Initially, I too faced similar error due to delay in redirect URI not updating instantly after configuration.

    When I tried again after some time, user flow ran successfully and gave token like this:

    If you've just made the updates, give it a bit of time (typically a few minutes) and try again as there will be delay to reflect.
