description	Postman API platform for testing and documentation. Use for API testing.

Postman

Postman is the complete API lifecycle platform. 2025 features AI Agent Builder (orchestrating multi-step workflows) and Postbot (AI driven testing).

When to Use

• API Development: Documentation, Mock Servers, and Monitors.
• Testing: Automated testing in CI via newman CLI.
• Collaboration: Workspaces and "Forks" of collections.

Core Concepts

Collections

Groups of requests. Can be run as a suite.

Environments

Variables ({{base_url}}) that change between Dev, Staging, and Prod.

Pre-request Scripts

JavaScript code that runs before a request (e.g. generating an HMAC signature).

Best Practices (2025)

Do:

• Use AI Agents: Build workflows that chain requests intelligently using natural language.
• Use Mock Servers: Design the API first, create a mock, and let frontend devs build against it before backend is ready.
• Use newman: Run collections in GitHub Actions.

Don't:

• Don't hardcode auth: Use "Auth" tab variables.
