HTTP

Communication between Client and Server: As long as each side knows what format of messages to send to the other, they can communicate with one another. The messages send in between are generally categorized into request and response messages. And, the most common protocol for communication is HTTP.

What is HTTP?

HTTP stands for Hypertext Transfer Protocol and is used to structure requests and responses over the Internet.

There are 4 basic HTTP verbs (operation) we use in requests to interact with server:

• GET — retrieve a specific resource (by id) or a collection of resources
• POST — create a new resource
• PUT — update a specific resource (by id)
• DELETE — remove a specific resource by id

A HTTP request, in addition to an HTTP verb, typically consists of:

• a header, which allows the client to pass along information about the request
• a path to a resource
• an optional message body containing data

What is API Endpoint?

HTTP requires data to be transferred from one point to another over the network. An API endpoint is the point of entry in a communication channel when client and server interacting.
