`message_reads` Webhook Event Reference

Breaking Change Notice

Effective May 8, 2019, the parameter seq will always be 0 for all Messenger webhook events. This deprecation was announced on November 8, 2016. After Jul 31, 2019 the seq parameter will no longer be included in the webhook events. To de-duplicate messages use the mid parameter.

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
   }
}
