About

Postman is an API client and platform: build requests, save them in collections, and run them as tests on your machine, in CI with the Postman CLI, or on a schedule as monitors. The free plan covers individual use; team collaboration needs a paid plan.

What you can do with it

Send and debug HTTP, GraphQL, gRPC and WebSocket requests
Run a collection's tests in CI with the Postman CLI
Schedule monitors that check API availability and correctness

Get started

Example

npm install -g postman-cli
postman login --with-api-key "$POSTMAN_API_KEY"
postman collection run <collection-id>
