I'm looking for a way to check if the correct integration permission has been ticked on the app settings as well as the Page webhook settings.
Is there a way to get what permissions does an app access token has? Specifically for Workplace custom integration. Just like me/permissions on graph api.
Update: I got it working as @Prateek said. Using https://graph.facebook.com/v7.0/community?access_token={accessToken}&fields=install
I also had the answer on how to get the page webhook events. Using https://graph.facebook.com/v8.0/app/subscriptions?access_token={accessToken} in this case it needed an app access token instead of page access token.
Try /community GET API
