FB messenger and FB Page API are returning errors

Update timeline

1. identified Aug 06, 2020, 09:07 PM UTC

   It seems Facebook Messenger is suffering a wide outage on its api. Contents are properly received in ED but outgoing messages are currently queued on our side as the API refuses them. Once FB fixes the problem, messages should be delivered. For more information on FB resolution https://developers.facebook.com/support/bugs/733783060776081/

   FB Messenger incident is still pending, Facebook replied in ticket https://developers.facebook.com/support/bugs/733783060776081/ FB Page api is also impacted by the incident and is returning error during when fetching contents from the page. This is blocking the synchronization of contents on many Facebook page we manage. Contents will be imported once FB fixes the api.
