What Postman provides:

API Network: The Postman API Network provides a central place for both API consumers and API producers to easily discover, explore, and share APIs.

The Postman API Network has two parts: a public network and a private network. The Postman Public API Network is open to the entire API community, while the Postman Private API Network is for your team only.

Design and Mock: Postman's mock API servers simplify design and planning, support split-stack development, and help you ensure that your API will run the way it's supposed to in production.

Documentation: Postman allows you to publish documentation quickly and easily. Postman automatically pulls your sample requests, headers, code snippets, etc. to populate your documentation page with dynamic examples and machine-readable instructions so you can easily share your API with the rest of the world

Monitors: It's easy to set up API monitoring in Postman. Postman API Monitoring allows you to review your API responses, availability, and performance with each run so you can ensure that your API is always healthy.

Automated Testing: Tests are automated by creating test suites that can run again and again. Postman can be used to automate many types of tests including unit tests, functional tests, integration tests, end-to-end tests, regression tests, mock tests, etc. Automated testing prevents human error and streamlines testing. 

Work Spaces: Workspaces allow you to organize your API work and collaborate with teammates. They act as a common working area where you can group your API projects together and use API builder to start defining APIs or generate API elements.

GET: methods retrieve data from an API.

POST: sends new data to an API.
