What is the main role of the Postman tool in API testing?

Postman is a tool for testing APIs that allows sending HTTP requests to a server and receiving responses. Its main role is to simplify the process of verifying the correctness of APIs without the need to write code.

With Postman, you can:

• Formulate requests with different methods (GET, POST, PUT, DELETE, etc.)
• Add headers, parameters, and request body
• Automate tests using scripts
• Save request collections for reuse

This helps quickly identify errors in APIs, verify business logic, and integration between services.
