I will create API automation tests in java rest assured or csharp restsharp

I will cover your REST API with automated tests and clear reports.

You choose the stack:

Java: REST Assured + JUnit 5 or TestNG

C#: RestSharp + NUnit

What I check:

Status codes, response body, headers, JSON schema

Positive and negative scenarios (invalid data, missing fields, auth errors)

Chained requests (create, read, update, delete)

Data-driven tests where it makes sense

Optional: waiting for async processing and verifying the result in a PostgreSQL database

What you get:

Test project with README and run instructions

Allure report

Postman collection on request

Please send your Swagger/OpenAPI file or API documentation, and I will propose the test list before I start.
