Before facebook last update I was using Facebook Send message API by passing user reference parameter and getting recipient id in response.
Now the Facebook Send message API not returns recipient_id in the response when we use recipient.user_ref or recipient.phone_number to identify the message recipient.
Now they are using the Page scope id parameter like this
recipient": {
"id": "<PSID>"
},
How can I get this page scope id? So i can pass this to send api?
