I'm using the Facebook Graph API to reply a direct message.
I have published my message issuing an HTTP POST request to /CONVERSATION_ID/messages with a valid access token.
But I receive the following error: 

{
  "error": {
    "message": "(#3) Unknown method",
    "type": "OAuthException",
    "code": 3
  }
}

The same test on the Graph API Explorer returned the same error.
Can anyone please help me out?

My Workplace (Facebook for business) GRAPH API application received a "(#3) Unknown method" error when it didn't have POST or DELETE permissions for the action it was attempting. Changing the integration/application permissions resolved the problem for me.

You don't need to add /messages to the API. Just call the API as https://graph.facebook.com/{message_id} to get the thread.
