Access public data of other users using Instagram/Facebook API

Question

I would like to access other users public data to show in my website when they configure the page by their username/id. It means I will create an app on FB/Instagram side and with the help of this app's access token I would like to fetch public data of other user.

Is this scenario valid now? Earlier it was possible but I am not sure now with changes in policies. Even the documents are not clear enough which can say it's possible or not?

Has anyone tried this out recently?

Answer 1

Users: Only data of users who specifically authorized your App is available, depending on the authorized permissions. It does not matter if data of user profiles is public or not, you have to get permission from each user separately.

Pages: If you want to get data of pages you don´t own, you have to go through a review process with your App to get access to "Page Public Content": https://developers.facebook.com/docs/apps/review/feature/#reference-PAGES_ACCESS

That´s for Facebook, about Instagram you can just hit the docs (as well): https://developers.facebook.com/docs/instagram-api/business-discovery
