FAQ
What do you need from me to start?
Your API base URL, the endpoint list, API documentation (Swagger, OpenAPI or a Postman collection if you have one), and test credentials or an API key. If you do not have documentation, I can build the Postman collection from scratch for you.
Do you test REST, SOAP and GraphQL APIs?
Yes. I perform manual and automation testing on REST, SOAP and GraphQL APIs across development, staging and production environments. If your API uses a different protocol, message me first and I will confirm before you order.
Will I receive the Postman collection and automation scripts?
Yes. On Standard and Premium you receive the complete Postman collection with automated test scripts and the Newman commands to run them, so your team can re-run the full suite anytime without me.
What exactly is included in the bug report?
Every bug includes steps to reproduce, the request and response screenshots, expected versus actual result, severity level, the affected endpoint, and a suggested fix. Reports are delivered in PDF or Excel, whichever you prefer.
Can you run API automation inside our CI/CD pipeline?
Yes. Premium includes Newman CLI automation configured for CI/CD tools such as Jenkins, GitHub Actions, GitLab CI or Azure DevOps, so your tests run automatically on every build
How many endpoints are covered in each package?
Basic covers up to 5 endpoints, Standard up to 15, and Premium covers unlimited endpoints. If you need more than Basic allows, you can add the extra endpoints extra or message me for a custom offer.
Do you test authentication and API security?
Yes. I test OAuth 2.0, JWT, API key and session-based authentication, plus authorization rules, token expiry, rate limiting and common input validation vulnerabilities.
Is my API data kept confidential?
Absolutely. All credentials, documentation and data are treated as strictly confidential, are never shared or reused, and I am happy to sign an NDA before we begin.
How fast will I receive my API test results?
Basic is delivered in 1 day, Standard in 2 days and Premium in 3 days from the moment I receive your API details. Need it sooner? Add the Extra Fast Delivery option and I will deliver Standard or Premium in 1 day.
Do you retest after my developers fix the bugs?
Yes. Every package includes revisions. Once your team pushes the fixes I re-run the affected test cases and send you an updated report confirming what is resolved and what still needs work.
