Bot start conversation first (FB Messenger or Slack)

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)_/¯

I see, Get_Started from messenger Could you please advice, how we could use set up in bot to Trigger first get start message ? Thank you

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:

{
  "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"
        }
      ]
    }
  ]
}

@lahsuk So do we need to hit only for the fist time or every time the conversation start ?

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