API ReferenceEvents and webhooks

Events and delivery history

Poll the event journal and replay webhook deliveries safely.

Read recorded integration events to recover notifications your application missed. Events remain available for 30 days. Read with GET, save the returned meta.next_cursor, and pass it into the next request. Empty pages are normal: wait longer between repeated empty reads, then poll again.

The event envelope identifies the event, its type and time, and the referenced resource. order.completed has a detailed, limited set of purchase fields. Other event types may have an empty data object. Retrieve the referenced resource when you need its current details; the event history is not a complete historical copy of every resource.

Signed cursors are tied to the selected store and exact filter set, so do not reuse a cursor with different filters. An expired cursor returns 410 cursor_expired with fallback.transport: "cursor_polling"; restart without the expired cursor.

Delivery replay sends a retained integration event to its configured webhook destination again. It creates a new delivery ID and keeps the original integration-event ID. It does not repeat the purchase, refund, or other business action. You cannot supply a different destination URL, payload, or query override.
