Postman REST API QA Testing

@Microlent

I have read through your API testing requirements. It is a clear and focused task. Good manual testing for a REST API is really about thinking through the edge cases that documentation might overlook. I will focus on ensuring every endpoint in your Postman collection behaves correctly under pressure. My process for this project: - Verify every status code and payload against your schema. - Push the boundaries of your data validation rules for both required and optional fields. - Break the endpoints with malformed JSON and missing headers to confirm error messages are actually helpful. - Add test scripts directly inside Postman so you can rerun these checks with a single click in the future. API testing experience: https://www.freelancer.com/portfolio-items/11354470-software-qa-testing-report I have handled over 44 projects with thousands of test cases. I specialize in finding the subtle logic errors that automated scanners usually miss. A few quick questions about the work: 1. Is there a specific auth protocol like OAuth2 or simple API keys that I should be aware of? 2. Do you have a deadline for when you need the updated collection and summary report back? I can start as soon as you send over the documentation. Open a chat and let me know when you are ready to send the files. ~ Rajesh

Hi, I’d be a strong fit for this REST API testing assignment. I have hands-on experience in manual API testing using Postman, including endpoint validation, request/response verification, schema checks, authentication testing, and negative scenario coverage. I can review the Postman collection, environment, and documentation, then create and execute positive, negative, and edge-case scenarios for each endpoint. I will focus on: • Correct status codes and response payloads • Required/optional field validation • Boundary value checks • Schema and data type validation • Missing/invalid token handling • Malformed JSON and bad input scenarios • Meaningful error messages and graceful failures I can also add inline Postman tests where practical, so your team can rerun key checks easily later. Deliverables will include: • Updated Postman collection/environment • Executed test coverage summary • Defect list with severity/priority • Clear reproduction steps and expected vs actual results Sample defect format: Endpoint: POST /users Severity: High Scenario: Missing required email field Expected: 400 with clear validation message Actual: 500 internal server error I’m detail-oriented, structured in reporting, and good at catching subtle API issues around validation, auth, and error handling. Available to start immediately. Thankyou

Hello, I can deliver the Postman REST API QA testing you need, efficiently and effectively. I'll thoroughly test your API, ensuring each endpoint functions as intended, with precise status codes and payloads. I'll validate responses against schemas, checking for boundary values and attribute rules. My focus will be on error handling, ensuring bad inputs, missing tokens, and malformed JSON trigger correct error codes and meaningful messages. I'll create and execute positive and negative test scenarios, noting edge cases and adding inline Postman tests for easy re-running. With 5+ years of experience, I'm confident in my ability to deliver a high-quality, comprehensive report detailing endpoints covered, scenarios executed, defects found, and severity/priority ratings. Thanks, Adegoke. M

@ukokab

I will manually test your REST API in Postman – functional only, no load tests. Every endpoint will be checked for correct status codes, response payloads, schema validation, and field rules. I will create positive and negative scenarios, boundary values, missing tokens, malformed JSON, and verify graceful error handling. You will receive an updated Postman collection with inline tests, plus a concise summary report (endpoints covered, scenarios executed, defects found, severity/priority). I have 10+ years of QA experience and a sharp eye for subtle API bugs. **Question:** Do you have a sample of the expected error response format (status code + message structure) I should use to validate error handling?

@fizaa170

I can thoroughly test your REST API in Postman by validating each endpoint, checking schema accuracy, and covering edge cases with both positive and negative scenarios, plus adding reusable test scripts for future runs. I’ll ensure errors return correct codes and meaningful messages. Is your API using any auth method like JWT or API keys? Do you already have a schema (Swagger/Postman docs) to validate responses against? Any critical endpoints you want prioritized first?

@jegaonline

@manoval09

Hi, I see you need someone to systematically test your new REST API in Postman — catching edge cases, confirming each endpoint behaves as intended, and identifying issues before it goes live. I'll test each endpoint across HTTP methods (GET, POST, PUT, DELETE), validate response codes and payloads against your API spec, and document test cases with clear pass/fail criteria. I use Postman's collection runner to execute tests consistently and generate detailed failure reports with screenshots — that way, any bugs are immediately reproducible and actionable for your development team. My first step: within 24 hours, I'll review your API documentation and set up a baseline Postman collection with smoke tests across your endpoints. This shows you my testing methodology and gives you early confidence in coverage. What's your timeline for launch, and do you have a preferred format for the test report? Best regards, Val

@MthokoD

I'll handle it, don't worry. Your Rest API deserves a meticulous user-centric testing approach to confirm every endpoint’s seamless functionality and foolproof error handling. I believe that testing isn’t just about ticking boxes but crafting a integrated safety net that catches even the slightest discrepancies in status codes, data schemas and boundary conditions. My expertises lie in manual API functional testing with deep fluency in crafting positive and negative scenarios directly in Postman and embedding automated inline tests to make future runs effortless. Although I am new to the Freelancer platform, I bring a wealth of real-world experience and a proven track record of successfully delivering projects beyond this platform. In a recent API test engagement my work uncovered critical edge cases for error handling and data validation that enhanced product stability and reduced live defects by 40%. My approach won client praise as i provided a clear and actionable summary report that aligned to priority and severity. Let's connect and explore how we can bring your vision to life. Regards, Ahead Solutions P.S. If you're not happy — which we doubt — you don't pay.
