403 Even Dashboard Shows Successful Login

Hello,
I am following the OAuth2.0 [Authorization Code Flow] with a integration for Zapier.
I can login on when auth0 login page shows up, but got 403 {
“error”: “access_denied”,
“error_description”: “Unauthorized”
}.
On the dashboard, under user activity, it shows a successful login.
Any help would be greatly appreciated.

Hi @sdfa,

Welcome to the Auth0 Community!

Can you please share more details about your integration? What request is returning this error?
