Before facebook last update I was using Facebook Send message API by passing user reference. I was getting this information by checking the checkbox during checkout in my store (Shopify) using Facebook.
Now the Facebook Send message API no longer returns recipient_id in the response for message sends that use recipient.user_ref or recipient.phone_number to identify the message recipient.
Now they are using the Page scope id syntax is
recipient": {
"id": "<PSID>"
},
i am using this API
How can I get this page scope id?
