Postman Tool
In plain terms
A platform for designing, testing, and documenting APIs.
Going deeper
Postman lets developers build and send API requests, organize them into collections, write tests, and mock endpoints. It's a staple of API development.
Under the hood
Collections, environments, and automated test scripts support full API workflows and CI.
Examples
API testing, request collections, mock servers, documentation, automation.
Think of it like...
Like a workbench for experimenting with and validating any API.
