messages Webhook Event Reference

This callback will occur when a message has been sent to your Page. Messages are always sent in order. You may receive text messages or messages with attachments.

Attachment types image, audio, video, file, reel, and ig_reel are the main supported types. You may also receive fallback attachments. A common example of a 'fallback' is when a user shares a URL with a Page, an attachment is created based on link sharing. For unsupported shares made by users to your Page a fallback with no payload might be sent.

You can subscribe to this callback by selecting message when setting up your webhook.
