What is Postman?
Turkish: Postman
Postman is an API collaboration platform for sending requests, organizing collections, writing tests, and sharing documentation.
What is Postman?
Postman is a workspace where API teams can send requests manually, save example responses, write checks, and share documentation. It can inspect anything from a simple GET request to an OAuth token flow or file upload scenario without writing a full client application.
Requests in Postman are organized into collections. Environment variables keep test, staging, and production URLs separate. Pre-request scripts and test scripts can automate token retrieval, data preparation, or response-field validation.
Where It Is Used
During API design, frontend, backend, mobile, and QA teams can work from the same collection. When an endpoint changes, example requests, expected status codes, error responses, and authentication notes can be updated in one place. Monitor and mock server features help test integration behavior without depending on the live system every time.
Business Use
Postman is often used to debug payment, shipping, CRM, ERP, and third-party service integrations. It is not a contract by itself; for long-term API quality, teams should pair it with an OpenAPI definition, clear REST API conventions, and automated API testing.
