REST Client is like a messenger that helps applications talk to a server that provides a RESTful API. It handles tasks such as sending requests for data, updating resources, creating new records, or deleting existing ones. Imagine you need to retrieve information from a remote server or update data in a database. REST clients act as intermediaries, helping your application send requests to the server and receive responses back.

In today's digital world, where systems need to work together smoothly and communicate effectively, two important terms come into play, APIs and web services.

Imagine you are sending a message to your friend, but you want to ensure that no one else can understand it. So lets say you are encoding your message using a special language that only you and your friend knows. This way, even if someone intercepts the message, they won't be able to understand its true meaning. The encoded message itself is what we call the "payload." In the world of APIs (Application Programming Interfaces), the concept of a payload is quite similar.
