Azure AD B2C Run User flow

Yash 86 Reputation points

Hi Azure Active Directory Community,

I'm have created a login user flow in AADB2C. I'm trying to run the flow to see how it works, but the "Run user flow" button is not working.

Can anyone please help me to understand what can be the possible issue?

    Thank you for your post!

    As a pre-requisite for using a B2C User Flow, you'll need to Register a web application in Azure Active Directory B2C and Enable ID token implicit grant. Once you've created your application, you can go back to your user flow, select the application, reply URL, and run the flow.


    If you have any other questions, please let me know.
    Thank you for your time and patience throughout this issue.
