Idempotency
Ensure retries cannot duplicate orders, payments, records or invoices.
System ownership
Choose which system is authoritative for each business object and life-cycle transition.
Execution observability
Record correlation IDs, request status, retries and reconciled external identifiers.
Recovery workflow
Provide a documented response to failed webhooks, authorization expiry and schema changes.
Testing
Test duplicate events, bad payloads, partial failures and realistic rate limits before rollout.
Putting the guidance into practice
Start by documenting the process and defining what counts as a successful, reversible and auditable result. Agree on permissions, decision ownership and operational metrics before activating the workflow.
