The role Webhooks plays
Webhooks commonly controls asynchronous updates from payment, email, automation, and SaaS providers. Its surrounding reliability depends on signatures, retries, idempotency, ordering, timeout, and durable event records, so the visible error may originate outside the file the AI last changed.
Specific failure patterns to inspect
For API Integration Not Working, common causes include authentication header, payload shape, quota, server-versus-browser execution. Generated implementations also tend to omit defensive error handling, version checks, idempotency, or a safe difference between public configuration and private credentials.
A safer diagnostic sequence
Preserve the current branch and exact error. Then save status code and response ID; read the provider log; confirm endpoint environment. Follow one test request across the interface, server or provider, and durable data rather than making several speculative code changes.
Repair boundaries
The repair should change the narrowest contract that is actually broken. Broader refactoring is justified only when duplicated ownership or an unsafe architecture would otherwise let the failure return.
What to avoid
Do not put a private key in browser JavaScript or retry failed writes without idempotency. Do not upgrade the entire Webhooks stack during a contained incident unless version incompatibility is the proven cause.
What a complete handoff includes
The handoff identifies the root cause, affected code or settings, safe test case, deployment note, and any remaining follow-up. The repaired behavior should be protected by a repeatable check.
