Overview

POSTMAN is a popular API (Application Programming Interface) development and testing tool used by developers and testers to interact with APIs. It provides a user-friendly interface for sending HTTP requests, viewing responses, and organizing API requests into collections for easy management and documentation.

Key Features:

• HTTP Methods: Supports all standard HTTP methods (GET, POST, PUT, DELETE, etc.).
• Parameters and Headers: Easily add query parameters and headers to requests.
• Request Body: Supports various body types (form data, JSON, XML, etc.).

Use Cases

POSTMAN can be used in various scenarios:

Collaboration

When two developers are working on the same project, one creating APIs and the other developing the frontend, POSTMAN collections can streamline the process. The backend developer can document and test the APIs in POSTMAN and share the collection with the frontend developer. This way, the frontend developer can test the APIs independently before integration without needing to delve into the backend code.

Testing and Debugging

Developers can use POSTMAN to test and debug their APIs. They can send requests with various parameters and headers to see how the API responds, helping identify issues before the frontend integration.

Documentation

POSTMAN enables developers to create detailed documentation for their APIs. This documentation can be shared with team members or external stakeholders, providing a clear understanding of how to use the APIs.
