API Testing & Collaboration Tool for Developers

Overview

Postman is a comprehensive API development platform enabling request building, automated testing (via JavaScript scripts), mocking, monitoring, and team collaboration. Its public workspace offers pre-built API collections for direct testing of REST, GraphQL, and SOAP endpoints. Users can inspect responses (JSON/XML), create test suites with assertions, and share collections. Use cases include validating API functionality, automating regression tests, simulating mock APIs for frontend development, and collaborating on API design.

Example Integration (JavaScript)

  .then(res => res.json())
  .then(data => console.log(data))
