The Facebook Messenger Identity Mapping API works for admins only
I have a messaging application and I want to check if the user of the messenger is also a registered user of my website. I am using id api function to get real facebook id using psid returned by messenger. However, it only works for me who is the admin of the application. When I use another custom psid to execute the request, I get blank data even though it's registered on my website with Facebook.
What could be the problem?
