"Get Started"

tried sending request to this url

But didn't work.

Answer 1

The current format is, https://graph.facebook.com/v2.6/me/messenger_profile?access_token=PAGE_ACCESS_TOKEN

{ 
  "get_started":{
    "payload":"GET_STARTED_PAYLOAD"
  }
}

Answer 2

It is possible you set it successfully, but are not seeing it because you already have an existing conversation with the facebook page.

After successfully setting the "Get Started" thread, you will only see it if you delete your existing conversation thread and start a new one.

Get started button is only shown when you are interacting with the facebook page for the first time, so if you have previously messaged the page, you will not be able to see "Get Started" unless you delete the thread from your Facebook Messenger client (either mobile or desktop).

From the FB Messenger Docs:

There are certain conditions to seeing the Welcome Screen and the Get Started button:

• They are only rendered the first time the user interacts with the Page on Messenger
• Only admins/developers/testers of the app can see it when the app is in development mode
• Your app must be subscribed to postbacks on your webhook
