Authentication failed! Twitter returned an error. 403 Forbidden: The request is understood, but it has been refused


#1

Hi,
in my developer account I have an APP “Mansion Fast Checkout”. We use the app and make our customer Login in our website.

It was working fine few days back. Suddenly last two weeks it is not working. I have tried all possible ways in coding and posted in twitter developer support but no responses.

The error I am getting is,

“Authentication failed! Twitter returned an error. 403 Forbidden: The request is understood, but it has been refused”.

I request you to check my APP and help me to fix this issue.

thanks

Have you checked this announcement? Action REQUIRED - Sign in with Twitter users must whitelist callback URLs

Yes sir I have checked this announcement recently. Can you tell me the process to whitelist the Callback URLs.

Do I need to do any setting changes in my application?
