Illustrative service shape
This is an illustrative application scenario, not a customer story or an offered managed stack. An illustrative webhook receiver with signature checks, a limited queue and safe handling of repeated events. Verify the sender signature before accepting a webhook, store an event identifier to make replay visible and send accepted work to a bounded queue. A response acknowledgement does not mean downstream work completed.
Run one bounded workflow
Receive a signed event, save its event ID, and enqueue only after the signature and expected source are checked. Use a small replay window and a safe response for a duplicate event.
Test the failure and return path
Simulate a slow downstream system. Confirm the receiver accepts no unlimited backlog and that a retry preserves one logical event rather than creating a duplicate outcome.
Leave a focused handover
Record the component owner, UTC exercise window, artifact or configuration revision, observed result and next review trigger. Link the selected profile and server-country decision from the operating record instead of copying commercial facts into this scenario.
