Verify API Behavior Across Every Endpoint with Functional Testing

Request/Response Validation

Ensure all APIs return correct, consistent data by validating status codes, headers, schemas, and payloads across edge cases.

Workflow/Chained API Testing

Validate multi-step API calls, chained responses, and authorization across microservices with robust assertion logic.

Schema & Contract Testing

Test for compliance with OpenAPI/Swagger standards and validate contract-based integrations across systems.

Frequently Asked Questions (FAQs)

It involves validating your API endpoints for correctness, stability, and adherence to business logic — including response data, schema, error codes, and workflows.

Each microservice communicates via APIs. Functional API testing ensures these communications don’t break or misinterpret data across distributed services.

Yes, we test both internal and external APIs to ensure integrations are reliable and compliant with SLA contracts.

Yes — we create automated suites using tools like REST Assured, Postman/Newman, and integrate with Jenkins/GitHub.

They should run with every build as part of CI/CD — especially when APIs are reused across features and clients.

Yes, we build realistic and secure test data sets to validate edge scenarios and negative paths.

Functional testing checks logic and behavior, while performance tests stress-load response times, and security tests check for vulnerabilities like injection, spoofing, etc.

Release Quality APIs, Every Time

No more trial and error — only test-driven confidence.
