Project:15-not getting post on fb

my request is send successfully and is recieved by webhooks successfully but fb is not posting it.it is showing error:401: OAuthException (190): Error validating access token: The user has not authorized application 576881582383647

In thyat case you have to look the correct authorized ID from bolt iot.you have to enter the correct credentials to authorize webhooks.

there is no description of authorizing id in the project in the course

now by doing all again i’m getting this error:403: OAuthException (200): (#200) If posting to a group, requires app being installed in the group, and
either publish_to_groups permission with user token, or both manage_pages
and publish_pages permission with page token; If posting to a page,
requires both manage_pages and publish_pages as an admin with
sufficient administrative permission

my fb was having my pages for which integromat wants permission and i don’t know how to do that so i created with twitter instead and it works!!!
so my problem is solved now.thanku
