API design & integration
Interfaces your teams can depend on.
Create versioned contracts, validate payloads and handle authentication, throttling and backwards compatibility.
- Request
- Typed fields and a stable resource identifier
- Response
- Documented result and error behaviour
- Evolution
- Compatibility rules and a deprecation path
An implementation example
The contract includes the failures
Design APIs around business capabilities, predictable validation and stable error semantics. Test consumers against the contract so changes can be released without guessing which integration might break.
A contract consumers can rely on
A portal and several integration clients update on different schedules.
A failure to account for
A new required field breaks an older mobile client that cannot update immediately.
Illustrative scenario, not a customer case study.
Integration & business systems
Predictable contracts for ordinary and failed requests.
Contracts and versions
Define requests, responses and error behaviour that consumers can validate before deployment.
Identity and limits
Apply authentication, authorisation and rate controls at each exposed interface.
Consumer compatibility
Test existing clients against changes and provide a clear transition for breaking updates.
A sample response cannot explain an API
The fragile approach
Publish an endpoint and a sample response
Consumers must infer pagination, retries, validation errors and compatibility from production behaviour.
The intended approach
Document the complete interaction
Version schemas, test representative failures and specify which commands can be retried safely.

No. Distinguish compatible additions from changes that alter meaning or remove behaviour. Versioning should make the migration clear, not replace compatibility analysis.
