Steps
Open the Gelato API Portal and configure a webhook URL that will receive HTTP POST requests over TLS; your endpoint must return a 2xx status.
Subscribe to events such as order_status_updated, order_item_status_updated, order_item_tracking_code_updated, and catalog_product_stock_availability_updated.
Parse the incoming JSON event, which always includes an id, event name, orderId (Gelato's ID), and orderReferenceId (your internal ID).
For order_status_updated, read the fulfillmentStatus and per-item fulfillments array (tracking codes, shipment method) to update your order records.
Return a 2xx response promptly; Gelato retries failed deliveries 3 times with a 5-second delay between attempts.
Known gotchas
No response body is read by Gelato — returning anything other than a 2xx status code is treated as a failure and triggers a retry.
Split orders (fulfilled from multiple production hubs) generate separate webhook events per connected order, all sharing the same orderReferenceId but different orderId values — aggregate by orderReferenceId in your system.
