Production Readiness Checklist
Final Review
Before declaring the API complete, verify:
- Resource names and URIs are consistent.
- HTTP methods have correct semantics.
- Status codes are meaningful.
- Errors are machine-readable.
- All input is validated.
- Authentication is secure.
- Authorization is enforced at resource level.
- Tenant boundaries are tested.
- Sensitive fields are never accidentally exposed.
- Rate limits exist for abuse-sensitive operations.
- Timeouts exist for network dependencies.
- Retries are bounded and idempotency-aware.
- Pagination prevents unbounded responses.
- Database queries are indexed and monitored.
- Caching behavior is intentional.
- ETags or concurrency controls are used where needed.
- API documentation is current.
- Contract and integration tests exist.
- Logs, metrics, and traces are available.
- Graceful shutdown and health checks work.
- Webhooks are signed and idempotent.
- Long-running jobs use asynchronous processing.
- API versions have a migration strategy.
- Security tests cover unauthorized access.
- The API has been tested under realistic load.
Course Completion
At this point you should be able to design, implement, secure, test, document, operate, and scale a production-grade REST API rather than simply create CRUD endpoints.
Key Takeaways
- REST API design is about contracts and architectural constraints, not just CRUD.
- HTTP semantics should be used intentionally.
- Security and authorization are part of API design, not features added later.
- HATEOAS is a formal REST constraint and can make state transitions discoverable.
- Production APIs require reliability, observability, testing, and scalability considerations.
