Monitoring and handling failures
Read a webhook's active flag, last delivery time and delivery log, notice when it has switched itself off, recover, and fill the gap from the API.
Best practices for production operation
Explains best practices for running a ReceiptRoller integration app in production — environment separation, monitoring, deployment, incident response, and keeping documentation in order.
Webhook is not being delivered

Designing resends, ordering, and idempotency
What counts as success, the retry rules (1 min, 10 min, 1 h, four attempts), ordering and lost events, and dropping duplicates by X-RR-Delivery.

Which webhook events are actually sent, what the request and signature headers look like, how duplicates, order and lost events behave, and when to use the API.
How to register a Webhook
Register a webhook in the developer portal or through the API, choose events that are actually sent, run a test send, and change, pause or delete a webhook.
