Frequently Asked Questions

API Testing validates whether your application’s APIs function correctly, securely, and efficiently. It ensures data integrity between services, identifies issues early, and guarantees consistent user experiences — making it critical in modern microservices and cloud architectures.

We provide comprehensive API testing services including Functional API Testing, API Security Testing, Load & Performance Testing, and API Mocking & Virtualization to test dependent services even before they are ready.

We leverage industry-leading tools including Postman, REST Assured, SoapUI / ReadyAPI, JMeter for API load testing, and Apidog for mocking and virtualization. We also integrate automated API tests within your CI/CD pipelines for continuous validation.

Absolutely. We perform thorough API Security Testing to detect vulnerabilities such as injection flaws, broken authentication, data exposure, and improper permissions — aligned with OWASP API Security Top 10 and regulatory standards such as GDPR, HIPAA, PCI DSS, or local compliance requirements.

Yes. We simulate high traffic to evaluate API scalability, responsiveness, and stability under peak loads. Detailed reports highlight throughput, latency, error rates, and system behavior under stress conditions.

We specialize in Shift-Left API Testing, integrating automated API tests early in your agile cycles and embedding them in your CI/CD pipelines (Jenkins, GitLab, GitHub Actions) for continuous validation and faster feedback.

Yes. We support multi-versioned API testing (v1/v2/v3), multi-environment testing (QA, UAT, Staging, Prod), and regression validation to ensure backward compatibility and consistent performance across all environments.
