What is API Documentation in Postman?

We can produce documentation for the APIs used in Postman by default.This document can be shared privately or publicly. Postman creates and hosts documentations on Collections which can be synced at the real time through the browser. Also, this documentation helps to share public APIs among teams and other stakeholders.
