Postman is a popular software development tool used for building, testing, and documenting application programming interfaces (APIs). It offers a comprehensive set of features that simplify the process of API testing and development. The primary purpose of Postman is to allow developers to make API requests and observe the responses in an organized manner. It provides a user-friendly interface where users can create requests with different HTTP methods (GET, POST, PUT, DELETE, etc.), add parameters and headers, and send them to the desired endpoint. Postman also supports authentication mechanisms like OAuth 2.0, which allows developers to securely test APIs that require authentication. Additionally, it enables the management of multiple environments (e.g., development, staging, production) for easy switching between different configurations. One of the key features of Postman is its ability to save and organize API requests into collections. This makes it convenient for teams to collaborate on API development and share their collections with others. Collections can be exported as JSON files or shared via URL links. Furthermore, Postman provides an extensive set of testing capabilities. Users can write automated tests using JavaScript in a pre-request scripting or test scripts section. These tests can validate response codes, response bodies, headers, and perform various assertions on the data. Postman allows users to generate detailed documentation for their APIs automatically. By including comments in the requests or using specific annotations in code comments (e.g., OpenAPI specification), developers can generate interactive documentation that includes request examples and explanations. Postman comes in both desktop (Windows, macOS, Linux) and web versions. The desktop version offers advanced features like team collaboration through workspaces, while the web version allows users to access their collections from any device with an internet connection. Overall, Postman has become an essential tool for developers working with APIs due to its user-friendly interface, extensive feature set for testing and documentation purposes, and its ability to streamline collaboration among team members. # References ```dataview Table title as Title, authors as Authors where contains(subject, "Postman") or contains(title, "Postman") ```
