Overview
REST APIs are often the simplest way to connect enterprise systems, but the long-term quality depends on contracts, error handling, security, and observability.
Integration Checklist
- Define request and response contracts
- Use clear authentication and authorization rules
- Version APIs deliberately
- Log correlation identifiers
- Document error responses
- Test realistic failure scenarios
Key Takeaways
The integration is not finished when the first successful request works. It is finished when failures are understandable, supportable, and recoverable.
