Postman

How it works

Postman sends requests to an API and displays the returned data, status, and headers. Collections group related requests, and variables let the same collection target different environments. Tests check expected behavior. Shared documentation and mock responses help people agree on an integration before every connected system is fully implemented.

What you can build

Create API test collections, shared integration documentation, mock services, and automated checks for application connections.

• Integration exploration

  Try a service request with sample data, inspect the response, and document the required fields before connecting the service to the application interface.

• Repeatable API checks

  Run a collection that verifies common workflows and error responses, helping a team detect changes in behavior as an application or integration evolves.

Things to consider

Collections are most useful when examples and checks stay current. Keep credentials out of shared exports and distinguish realistic test cases from successful sample requests.
