Helpdesk API Request Lifecycle

Audience

Developers, QA, support and architects.

Summary

Minimal API handlers bind route/query/body data, resolve injected dependencies, apply distributed validation, query/mutate EF Core entities, add activity and events where applicable, save and return typed result objects.

Reference Content

Notification/outbox write path

Tenant/domain validation exceptions are mapped to client errors by middleware. Document dependency errors are handled in attachment operations and returned as dependency-unavailable problems.

Requires confirmation

Transaction/concurrency policy, idempotency, downstream event delivery and standardized error envelopes require confirmation.
