Hello @Mohamed Umair Mohamed Anhar

Based on your application configuration, you should get redirected to https://test.b2clogin.com/test.onmicrosoft.com/oauth2/v2.0/authorize? endpoint for authentication along with few extra parameters, such as:

• client_id
• nonce
• redirect_uri
• scope
• response_type

And the complete redirect URL should look like this:
https://test.b2clogin.com/test.onmicrosoft.com/oauth2/v2.0/authorize?p=B2C_1A_signup_signin&client_id=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx&nonce=defaultNonce&redirect_uri=http://localhost:4200&scope=openid&response_type=id_token&prompt=login

Once B2C completes the authentication process, it posts the reponse based on response_type parameter which can be code, id_token or token to the redirect_uri, which is localhost:4200 in your case. When the response is posted by B2C, you should automatically get redirected to localhost:4200. For www.example.com, the redirect_uri must be set to www.example.com.

Here is a sample for Single page apps. If you have Mobile and desktop app or Web app and API, you can refer to the samples here: https://learn.microsoft.com/en-us/azure/active-directory-b2c/code-samples
