Handling Different Request Types

Postman’s versatility extends beyond creating and sending API requests. It’s equally proficient in handling various request types, allowing you to interact with APIs comprehensively. In this guide, we’ll explore how to effectively work with different request types like GET, POST, PUT, DELETE, and more using Postman.
