What Is Postman Used For?
- Sending HTTP requests (GET, POST, PUT, DELETE) to test REST APIs during development.
- Organizing API requests into collections for team collaboration and documentation.
- Writing automated API tests with Postman's built-in test scripting (JavaScript-based).
- Generating API documentation from collections and sharing it with stakeholders.
- Mocking API responses to unblock frontend development when the backend is not ready.
Workflow Tips
Get more out of Postman with these practical workflow patterns:
- →Create a Postman Environment (top-right gear icon) and store variables like {{baseUrl}}, {{authToken}}, and {{apiKey}}. Switch between dev, staging, and production by changing the active Environment from a single dropdown.
- →Organise requests into Collections — export the Collection as a JSON file and commit it to your repository so the whole team shares the same API test suite and examples.
- →Use the Pre-request Script tab to generate or refresh auth tokens automatically before each request runs, eliminating the need to manually copy-paste JWT tokens.
- →The Tests tab accepts JavaScript assertions against the response (e.g., pm.response.to.have.status(200)). Run the full collection headlessly via the Newman CLI to execute API tests in your CI/CD pipeline.
Common Issues And Fixes
Check the problem and the exact fix before you reinstall anything. Some guides also include the reason the issue happens.
Problem
Postman does not appear in Start Menu after installation
Exact fix
Postman installs to %LOCALAPPDATA%\Postman. Restart Windows Explorer or search for "Postman" in the Start Menu search. The installer creates a shortcut automatically.
Problem
Requests fail with SSL certificate errors
Exact fix
Disable SSL certificate verification in Settings → General → SSL certificate verification (for development only). For production-like testing, import your CA certificate via Settings → Certificates.
Problem
Postman is slow or consumes too much memory
Exact fix
Postman is an Electron app and can be memory-intensive. Close unused tabs and minimize the number of open collections. Consider using the lightweight Postman CLI for automated testing.
Problem
Cannot connect to localhost APIs
Exact fix
Ensure your API server is running and listening on the correct port. If using Docker, check that port mapping is configured. Try http://127.0.0.1:port instead of http://localhost:port if DNS resolution is an issue.
Tips for Postman
- ✓Postman is a GUI application and does not add itself to PATH — it is launched from the Start Menu or desktop shortcut.
- ✓Use Postman Environments to manage variables like API base URLs and auth tokens across development, staging, and production.
- ✓Export collections as JSON files to version-control your API tests alongside your source code.
- ✓For CI/CD integration, use Newman (Postman's CLI runner): "npm install -g newman" and "newman run collection.json".
