Hi @OliverRodrigues ,
I did check the redirect URL and it work perfectly fine when I login into portal via the portal login button itself.
The scenario is that there are couple of external facing websites . Currently, I have embedded the local authentication method in my website which on click of a button open the portal login page in an iframe and after successful login external customer can interact with data staying within the iframe within the external website.
However, I have now decided to change the authentication method from local to B2C. Hence, trying to replicate the current functionality with B2C. Struggling!
Below is a snap on how the local authentication page loads and after successful sign in the user can interact with the data staying in the same iframe.
