What to know

Treat an event as a notification

Overskill’s developer reference documents webhook management. A webhook tells your integration that something happened; it should not be treated as permission to repeat an irreversible action whenever a message appears. Start by naming the event, the record it concerns and the exact change your receiver is allowed to make. For a request tracker, that might be notifying an operator about a newly submitted request, not recreating the request or charging someone because an event was delivered twice.

What to know

Define identity and duplicate behavior

Ask what stable event or operation identifier the actual service supplies, and retain it with the processing result. Do not invent a header name or retry guarantee that the documentation does not establish. In a local design exercise, deliver the same fictional event twice and describe the expected outcome. A second notification may be annoying; a duplicate financial or data mutation can be much worse. The receiver should distinguish a completed action from one whose outcome is still unknown.

What to know

Recover a missed notification deliberately

Decide how an operator would find an event that never reached the receiver. A supported status or record read can help reconcile state, but only if it actually exists for the workflow. Polling indefinitely or repeatedly submitting the action is not a recovery plan. Record a bounded retry rule, an uncertainty state and a clear stop condition. Keep any service credentials server-side and scoped appropriately; this article does not authorize creating them or expose a working integration endpoint.

What to know

Test the failure cases before automation

Use fictional data to consider delayed delivery, duplicate delivery, an unavailable receiver and an unexpected event type. For each case, state what is saved and what a person can safely do next. Keep logs free of full private payloads when a reference ID and error category are enough. These are original design checks, not claims about Overskill’s delivery semantics or measured reliability. Only turn on a real workflow once its documented contract and permitted recovery behavior are clear.
