Selenium WebDriver acts as a bridge between automation scripts and the browser.

Selenium WebDriver communicate with the browser to perform actions, It uses the WebDriver protocol to send commands from your script to the browser and retrieve responses.

WebDriver protocol (W3C - World Wide Web Consortium) is a communication standard with set of rules and APIs.

Rules:

Client-Server architecture:

1. The client sends HTTP requests to the server, and the server (browser driver) responds with HTTP responses.

HTTP Methods:

1. HTTP (Hypertext Transfer Protocol) methods like GET, POST,…etc.

Endpoints:

1. Each endpoint points to a specific browser automation command (e.g., navigating to a URL, clicking an element).

JSON Payloads:

1. Requests and responses contain JSON payloads for passing and receiving data.

Components of an API :

HTTP Methods : GET, POST,..ect

Endpoints (URLs):

Request Parameters

Authentication & Authorization

HTTP request client (web browser or an app) communicates with a server, asking for a resource or performing an action. It contains:

1. Method: Indicates the action (e.g., GET, POST, PUT, DELETE).
