I’m working on a new project working as Social Media Planner. I want to connect users’ accounts to my App to be able to publish on their behalf.
I created the app on facebook, and it has been approved.
I’m using Laravel 11 + Vue 3 + PHP SKD kit suggested by Facebook Docs.
The Consent page is loaded successfuly. But after redirection I’m getting error message “Authorization headers are required”.
