About this Gig
Need reliable REST API testing before release?
I will professionally test your API using Postman, covering functional, negative, authentication and integration scenarios. I can validate responses, status codes, payloads, headers, OAuth/API keys and common error conditions, then provide clear defect findings and a summary report.
With 12+ years in QA and quality engineering, I bring hands-on experience with REST APIs, Postman, Apigee, Azure DevOps and enterprise integration testing.
Depending on your package, I can also support regression coverage, basic API security validation and performance checks.
Please message me before ordering if your API has a large number of endpoints or complex authentication/integration requirements.

FAQ
What do you need from me to start API testing?
I usually need the API documentation or endpoint list, base URL, authentication details, expected behaviour and any relevant test data. A Postman collection or OpenAPI/Swagger specification is helpful if available.
Can you test authenticated APIs?
Yes. I can test APIs using common authentication methods such as OAuth, bearer tokens, API keys and other access-control mechanisms, provided you supply valid test credentials and access.
Do you provide a test report?
Yes. I provide clear findings covering the scenarios tested, defects identified, severity where appropriate and supporting evidence such as request/response details or screenshots.
Can you create or improve my Postman collection?
Yes. I can create, organise or improve Postman collections, including variables, environments, assertions and repeatable regression checks. Please contact me first if this is a major part of the requirement.
Can you test performance or load as well?
Yes. I have experience with JMeter and K6 for API performance testing. For significant load or performance testing, please contact me first because scope depends on expected users, traffic levels and the environment available.
Do you perform penetration testing?
This Gig covers API quality testing and basic security-related validation such as authentication, authorisation behaviour, negative scenarios and access controls. It does not include full penetration testing or an accredited security assessment.
Can you test Apigee APIs or APIs exposed through any other API gateways?
Yes. I have hands-on experience with Apigee API Management, including API proxies, authentication, policies, integrations and consumer/provider testing. For Apigee-specific work, please message me with the scope before ordering.
