I will do API testing, postman collection, rest API QA, and backend bug report
Ethan R
About this gig
Broken APIs, slow response times, and unhandled status codes directly ruin application performance and user trust. I provide end-to-end API testing, REST API QA, and comprehensive Postman collection setup to ensure your backend services are secure, reliable, and production-ready.
As a dedicated QA testing specialist, I rigorously inspect your backend endpoints, validate JSON/XML responses, and build organized test collections to eliminate silent backend bugs before they disrupt your software.
What I Will Do For You:
- REST API QA: Complete endpoint verification, status code checks, and response validation.
- Postman Collection: Standardized collections with pre-request scripts and dynamic variables.
- Automated Assertions: Custom JavaScript test scripts to validate headers, tokens, and payloads.
- Backend Bug Report: Detailed report with reproduction steps, error logs, and metrics.
- Performance Checks: Audit response latency and payload efficiency across endpoints.
- Auth & Security Audit: Validate Bearer tokens, OAuth, and authorization rules.
Stop backend errors from breaking your app. Choose your package and order directly now, or message me for a custom API testing setup!

FAQ
What do I need to provide for you to test my REST API?
Simply provide your API endpoints, base URL, API documentation (Swagger/OpenAPI if available), and required access credentials or authentication tokens (such as Bearer tokens or API keys). If you don't have full documentation, you can provide a list of routes or a sample curl request.
Will I receive a usable Postman Collection file after testing?
Yes! I deliver a fully configured Postman collection (JSON format) complete with organized request folders, environment variables, dynamic parameters, and custom JavaScript test assertions. You can easily import this file directly into your own Postman workspace to re-run tests anytime.
What is included in the backend bug report?
Your deliverable includes a structured PDF bug report featuring exact request/response payloads, HTTP status codes, latency metrics, failed test assertions, and clear step-by-step instructions for your backend development team to reproduce and fix the issue quickly.
