API Performance Test

Use a short API performance test to catch slow endpoints, timeout behavior, and unexpected status codes.

Start a safe test

What To Measure

Focus on p95 latency, p99 latency, failed requests, timeout count, status-code breakdown, and request throughput. These metrics show whether the API stays correct and fast enough under a small controlled burst of traffic.

When To Run It

Run tests before launch, after infrastructure changes, before a traffic campaign, or when validating a small API performance fix. Save the first report as a baseline and rerun the same settings after each change.

Safe API Testing

Test only endpoints you own or have permission to test. Prefer read-only routes, sandbox accounts, or idempotent actions when repeated requests could modify production data.
