The article provides information for preventing the following error that occurs when trying to import images from Facebook using the Image Gallery Feature:
Whoops! There's been an issue with the Facebook API while attempting to process your request. Please contact our support team!((#10) This endpoint requires the 'manage_pages' permission or the 'Page Public Content Access' feature or the 'Page Public Metadata Access' feature. Refer to https://developers.facebook.com/docs/apps/review/login-permissions#manage-pages, https://developers.facebook.com/docs/apps/review/feature#reference-PAGES_ACCESS and https://developers.facebook.com/docs/apps/review/feature#page-public-metadata-access for details.
This error occurs when the Facebook account in use does not have
manage_page privileges or the page is not public. The manage_page permission enables your app to retrieve page access tokens for the pages and apps.
Note: Since this error is related to the Facebook account permissions, BiznessApps support cannot help you to adjust these permissions.
You can do the following to prevent this error from occurring:
Ensure that the Facebook URL that you are using is for the main page and not a specific feature of the page;
Adjust the page settings to make the page publicly viewable without requiring a login; and
- Allow read-only access to public data on the page that does not have
manage_pagelogin permission. This readable data includes business metadata, public comments, and posts.
Note: For more information, refer to this article about Facebook Pages.
