After completing API testing

- [ ] All endpoints tested under baseline

- Define success criteria: target response times

- Test webhook delivery

- Information disclosure in error responses: stack traces

- Authentication weaknesses: token leakage

- Inadequate retry logic: no retries

- **Error Rates**: 5xx errors <0.1%

- **Throughput**: Read-heavy APIs >1000 RPS per instance

- **Resource Utilization**: CPU <70% at expected load

- Configure meaningful alerts based on SLI/SLO thresholds (e.g.

- **Response Time**: Simple GET <100ms (p95)

- Set up comprehensive API metrics: request rate

- Test proper error propagation: errors are meaningful

- Test error response consistency: correct HTTP status codes

- Identify resource bottlenecks (CPU

- Profile endpoint response times at baseline load

- **Establish observability** by setting up API metrics

- **Execute load and stress tests** by simulating realistic user behavior

- **Profile endpoint performance** by measuring response times under various loads

- **Validate API contracts** against OpenAPI/Swagger specifications
