I will test your rest API and deliver a detailed bug report
About this Gig
Need confidence your API works before it goes live? I'll test your REST endpoints thoroughly and report every bug, with clear evidence your developers can act on.
What you get:
- Functional testing of each endpoint: status codes, response body, headers and error handling
- Auth and permission checks (tokens, roles, expired sessions)
- Validation and edge cases: missing fields, wrong types, boundary values
- Performance/load testing: response times under concurrent requests (Standard and Premium)
- A Postman collection, or an automated test suite you can rerun (Premium)
Clear bug reports include the request, expected vs actual response, and severity.
Works with any REST API, with Swagger/OpenAPI docs or a Postman collection to start from. Perfect for startups and small teams before a release or integration.

FAQ
What do I need to provide?
The base URL of a test or staging environment, API docs (Swagger/OpenAPI or a Postman collection), and test credentials or API keys for that environment.
Will you test on my live production API?
I recommend a test or staging environment, especially for load testing, so real users and data aren't affected. I'll agree request limits with you before any performance test.
What will the bug report include?
For each bug: the endpoint and request, expected vs actual response, severity, and steps to reproduce. Performance results include response times and error rates.
Do you test GraphQL or SOAP APIs?
This gig is for REST APIs. Message me with details of other API types and I'll let you know if I can help.
