Postman Overview
What is Postman about?
Postman provides a comprehensive API platform that enables developers to create, share, and collaborate on API specifications, collections, mock servers, documentation, and automated tests. It supports both a native desktop application and a browser‑based experience, plus a suite of CLI utilities for CI/CD integration.
How to use Postman?
- Desktop or Web – Download the appropriate installer for Windows, macOS, or Linux, or sign up for a free web account.
- Create a workspace – Organize APIs, collections, and environments.
- Import or design specs – Use Spec Hub to write OpenAPI/AsyncAPI files, or import existing definitions.
- Build collections – Assemble requests, add scripts, and set test assertions.
- Run tests – Execute collections locally via the app, or use the Postman CLI / Newman for automated pipelines.
- Generate docs & mocks – Publish interactive documentation and mock servers for stakeholder review.
Key features of Postman
- Spec Hub – Central source of truth for OpenAPI and AsyncAPI specs with real‑time validation.
- Collections & Workspaces – Structured request groups with shared environments.
- Postman CLI & Newman – Command‑line runners for CI/CD, linting, and security checks.
- AI Agent Builder & Postbot – AI‑assisted assistance for request generation and testing.
- Integrations – Connectors for Git, CI tools, monitoring services, and more.
- Enterprise controls – Governance, role‑based access, and SSO for large organizations.
Use cases of Postman
- API development – Design, test, and iterate on REST or GraphQL APIs.
- Automated testing – Run regression suites in CI pipelines using Newman or Postman CLI.
- Documentation – Publish live API docs that stay in sync with specs.
- Mocking & prototyping – Provide temporary endpoints for front‑end teams.
- API governance – Enforce standards and security policies across teams.
