Hi @mahmoud-turki,

Thank you so much for quick reply, but when I set the returnUrl like document, it open the sandbox webview to login sandbox account, but I can not login to dashboard. But when I go to the url sandbox.paypal.com I can login properly, so please help me.

It always say information isn't correct. But when I go to url sandbox.paypal.com I can login properly

Hi @tgloc96 , I think this could be related to a cache issue on the Sandbox developer account when you added the new return url.

I was able to reproduce the issue myself on Sandbox just after I changed the return url and, after a couple of hours , I was able to successfully login. Please try again, at this point in time you shouldn't have any cache issue. Please confirm if this worked for you. Thank you for your feedback and collaboration.
