Postman offers a straightforward interface for developers to design, build, and modify APIs. It lets you set headers, body content, parameters, and supporting HTTP methods such as GET, POST, PUT, and DELETE.

Postman offers an excellent testing framework for APIs that lets developers create and execute test cases, run automated tests, validate API responses, etc. It also supports test data management, scripting, and assertions.

Moreover, Postman is a great tool that facilitates collaboration. It allows teams to share documentation, APIs, and collections. Postman makes it easier for API development teams to work together using its collaboration features and version-control capabilities.

Another advantage of Postman is its ability to generate comprehensive documentation. Postman automatically generates documentation with descriptions, request examples, and response details and enables sharing it with consumers easily.

Postman can be integrated with popular development tools like Git, Newman, and Jenkins. Other than that, Postman supports many other extensions and integrations to enhance its customization capabilities and functionalities.

Postman allows developers to create mock environments without real backends to simulate API endpoints and responses. Finally, it offers monitoring capabilities for API performance tracking and availability.
