API and HTTP: A Quick Primer

The Application Programming Interface (API) serves as an intermediary between two software applications, facilitating their interaction. In the context of Postman, APIs allow functionalities such as Digest authorization, Basic authorization, Bearer token, Hawk authentication, API keys, and AWS signature.

Hypertext Transfer Protocol (HTTP), on the other hand, is the protocol used to access and transfer data on the world wide web, ranging from text, video, audio, and more.

What are the Limitations of Using Postman File Uploads?

What are Collections in Postman?

These are set of API requests stored in the Postman and can be assembled in a folder. The collection doesn’t have a specific amount of folders that it will contain. Collections assist the user to better document their request.

Benefits of Collections

These are some of the benefits or reasons why you need a collection:
