Postman is an API platform that enables users to build, test, and interact with APIs by sending HTTP requests and viewing responses directly within the tool. It provides a graphical interface for designing and managing sequences of API interactions, allowing users to create and organize related API requests into named collections for reuse and sharing.
The platform supports automating API workflows through test scripts and built-in sequences, and facilitates collaboration by enabling teams to share collections, specifications, and workflows. Users can document APIs by attaching descriptions and HTML notes to requests within collections, and export them for team coordination. Environment switching allows for changing API settings like URLs and credentials across different setups, while built-in authentication helpers support adding Basic Auth or OAuth 1.0 credentials to requests for secure access.
