I’ve been working around to let the bot start the greeting message first (example --\> postback button) in Facebook Messenger or Slack, but I couldn’t find an exact way yet. Anyone experience such a thing ?

I do not think this is possible in messenger. You could do it using the `Get Started` postback button. But other than this, I don’t think there are other ways.  
As for slack, I don’t know. `¯\_(ツ)_/¯`

You need to hit this API with your API token `https://graph.facebook.com/v2.6/me/messenger_profile?access_token=<token>`

And the body would look something like this:

```auto
{
  "get_started": {"payload": "/get_started"},
  "persistent_menu":[
    {
      "locale":"default",
      "composer_input_disabled": false,
      "call_to_actions":[
        {
          "title":"Home",
          "type":"postback",
          "payload":"/home"
        },
        {
          "title":"Change Language",
          "type":"postback",
          "payload":"/ask_languages"
        },
        {
          "title":"Chat with Live Agent",
          "type":"postback",
          "payload":"PAYLOAD"
        }
      ]
    }
  ]
}

```

You can read more about the persistent menu here:  
[get\_started - Messenger Platform - Documentation - Facebook for Developers](https://developers.facebook.com/docs/messenger-platform/reference/messenger-profile-api/get-started-button) ,  
[persistent\_menu - Messenger Platform - Documentation - Facebook for Developers](https://developers.facebook.com/docs/messenger-platform/reference/messenger-profile-api/persistent-menu)

Hope that helps.

You only need to set this up once (per facebook page).
