standby Webhook Event Reference

Updated: Sep 25, 2024

For bots using the handover protocol and conversation routing, this callback will occur when a message has been sent to your page, but your application is not the current thread owner.

Instead of delivering the callback through the normal messaging channel, the events will be delivered to standby channel. You can receive message, read, and delivery events through history messages.

You can subscribe to this callback by selecting the standby field when setting up your webhook.

Supported Events

The following events are delivered to the standby channel:

• message_reads
• message_deliveries
• messages
• messaging_postbacks

Note that messaging_postback events delivered via the Standby channel will not include the postback payload. The app that originally sent the postback button will receive the normal messaging_postbacks webhook event that includes the postback payload.

Example Event

{
  "object":"page",
  "entry":[
    {
      "id":"<PAGE_ID>",
      "time":1458692752478,
      "standby":[
        {
          "sender":{
            "id":"<USER_ID>"
          },
          "recipient":{
            "id":"<PAGE_ID>"
          },

          ...
        }
      ]
    }
  ]
}
