How to add 'Get Started' button in facebook messenger chat bot?

Question

I tried using this

curl -X POST -H "Content-Type: application/json" -d '{ "get_started": {"payload": "qr"} }' "https://graph.facebook.com/v2.6/me/messenger_profile?access_token=myPageAccessToken"

In response I also got { "result": "success" }

But the bot does not show any button.

First, make sure that your account facebook who try to use your bot since only admins/developers/testers of the app can see it when the app is in development.

Second, if you use Android, you need to clear the Messenger data/cache under Android Settings -> Apps, this will also clear your login and you need to login again.

It was working fine, All I had to do was, deleting the existing conversion.

In my case, get started button only appears, when there's no message exists in past.
