FAQ
What types of APIs do you test?
I test REST APIs, GraphQL APIs, SOAP APIs, and other web services. I can also work with APIs documented using Swagger/OpenAPI or Postman collections.
What tools do you use for API testing?
I primarily use Postman, Swagger/OpenAPI, Insomnia, and other industry-standard API testing tools. If you have a preferred tool, I can use that as well.
What do you need to get started?
Please provide your API documentation (Swagger/OpenAPI), Postman collection, API endpoints, authentication credentials (if required), and any specific testing requirements.
Will you provide a bug report?
Yes. Every order includes a detailed bug report outlining any issues found, expected vs. actual results, and recommendations for fixing them.
Do you test APIs that require authentication?
Yes. I can test APIs that use API keys, Bearer Tokens, JWT, OAuth 2.0, Basic Authentication, and other common authentication methods.
Can you test both staging and production APIs?
Yes. I can test development, staging, QA, and production environments. However, I recommend using a staging environment whenever possible to avoid affecting live users.
Do you perform performance or load testing?
Yes. Basic performance testing is available in the Standard package, while more comprehensive performance testing is included in the Premium package.
Can you create Postman collections and test cases?
Absolutely. I can create or update Postman collections, write organized test cases, and document the testing process for your team.
What if I have more API endpoints than your packages include?
No problem. Simply contact me before placing your order, and I'll create a custom offer tailored to the number of endpoints and the scope of testing.
Why should I contact you before placing an order?
Every API is different. Discussing your project first helps me understand your requirements, estimate the testing effort accurately, and recommend the most suitable package for your needs, ensuring you receive the best results.
