Frequently Asked Questions
-
Why is API automation testing critical in modern applications?
APIs connect services, devices, and platforms. Testing them ensures backend stability, prevents integration failures, and guarantees accurate data exchange—without relying on slow, manual checks.
-
Do you test both internal and third-party APIs?
Yes. We validate your in-house APIs and also test external integrations like payment gateways or CRMs—ensuring end-to-end reliability across internal and partner ecosystems.
-
How do you handle authentication and security in tests?
We manage OAuth tokens, headers, and encryption securely during test runs. Our test suites simulate real-world access patterns without compromising API security.
-
What tools do you use for API automation?
We use Postman for functional testing and Rest Assured or Karate for code-based tests—tailored to your stack and suited for scaling across hundreds of endpoints
-
Can you help us set up API test automation from scratch?
Yes. We define scenarios, create scripts, integrate tests into CI/CD, and maintain them over time—ensuring seamless coverage even if you’re new to API testing.
