Deprecated in v6.0 - Use Send API instead

On February 4th, 2020, we announced the deprecation of this POST endpoint on v6.0 of Graph API. On June 30th, 2020, it will be removed from all versions of the API. Please use Send API instead.

This endpoint only allows plain text messages, while the Send API allows apps to send Templates and Quick Replies among other rich messaging features. If you use the Conversation API to send a message outside of the 24 hour window, you may only send messages that fall within the approved use cases of the message tags described here
