Postman
Postman is a platform for building, testing, and documenting APIs, letting developers send requests, write automated test scripts, and share API collections across teams.
What Postman is used for
Postman started as a tool for manually sending HTTP requests and has grown into a full API workspace. Teams use it to explore and debug endpoints, organize requests into collections, write test assertions in JavaScript, run collections automatically with its Newman CLI in CI pipelines, mock APIs before they exist, and publish API documentation. It supports REST, GraphQL, and other protocols, making it a common hub for everything API-related on a project.
Why it matters for business software
Modern business systems are held together by APIs: between frontend and backend, between microservices, and with third-party providers like payment and CRM platforms. Postman gives teams a shared, versioned source of truth for how those APIs behave, which reduces integration bugs and onboarding time. Automated collection runs catch breaking API changes before partners or frontends do, and good API documentation lowers the cost of every future integration.
How Wizcoder AI Labs uses it
We use Postman collections on most backend and SaaS engagements to document APIs as they are built and to run contract-style checks in CI. It is a standard part of our testing and QA toolkit alongside unit and end-to-end suites.
