Manual API Testing with Postman for reliable, production-ready APIs
Is your API behaving as expected across different requests, inputs, responses, and error conditions? I will manually test your API endpoints using Postman to identify functional issues, unexpected responses, validation problems, authentication issues, and edge-case behavior.
What I Test
- API endpoints & request methods
- Request parameters, headers & payloads
- HTTP status codes & response validation
- Authentication & authorization
- Error handling & negative scenarios
- Input validation & boundary conditions
- API workflows and dependent requests
- Exploratory API testing
What You Receive
Clear, actionable API bug reports with reproduction steps, expected and actual results, impact, severity, priority, recommendations, and supporting screenshots or screen recordings when applicable.
Additional QA Documentation
Test cases and structured API QA checklists are available separately as paid extras.
Send me your API documentation, Postman collection, endpoints, or testing requirements to get started.

FAQ
What types of APIs can you test?
I can manually test REST APIs and API endpoints using Postman, including requests, responses, parameters, headers, authentication, validation, error handling, negative scenarios, and edge cases.
What do you need from me to start API testing?
Please provide your API documentation, Postman collection or endpoint details, required credentials, test data, and any specific testing requirements or workflows you want prioritized.
What will I receive after the API testing?
You'll receive clear API bug reports with reproduction steps, expected and actual results, impact, severity, priority, recommendations, and supporting screenshots or recordings when applicable. Test cases and QA checklists are available separately as paid extras.
Can you test APIs with authentication?
Yes. I can test APIs using supported authentication methods and verify authorization behavior, access restrictions, invalid credentials, expired sessions, and other authentication-related scenarios.
Can you test negative and edge-case scenarios?
Yes. Depending on your package, I can test invalid inputs, missing parameters, boundary values, unexpected data, error responses, interrupted workflows, and other edge cases to identify potential API issues.
