`message_reads` Webhook Event Reference

Breaking Change Notice

Effective February 19, 2018, this webhook event will no longer be triggered by message sends that use recipient.user_ref or recipient.phone_number to identify the message recipient.

This event will be sent to your webhook when a message a Page has sent has been read by the user.
You can subscribe to this callback by selecting the message_reads field when setting up your webhook.

The message_reads webhook event is not supported for messages sent via the Broadcast API.

Example

{
   "sender":{
      "id":"<PSID>"
   },
   "recipient":{
      "id":"<PAGE_ID>"
   },
   "timestamp":1458668856463,
   "read":{
      "watermark":1458668856253,
      "seq":38
   }
}
