Receiving Webhook Requests

Webhook events arrive as a POST requests, usually within 1 minute of the triggering event.

Webhook requests that return a 4XX or 5XX status code will retry up to 5 times at 30 minute intervals until a 2XX status code is returned.

Below is an example webhook payload.

{
  "data": {...}, // Webhook event data
  "deliveryAttempt": 1, // Times we have sent this event, including this attempt
  "pendingRetries": 4, // Times we will re-attempt to send this event if this attempt fails
  "eventType": "shipment.purchased",
  "sentAt": "2019-03-19T17:42:59.745Z" // ISOString datetime that we sent this webhook event
}

The contents of data will vary by webhook event type. More information can be found at the links below.
