Right Answer:
Webhooks are user-defined HTTP callbacks that are triggered by specific events in a web application, allowing real-time data transfer. They differ from APIs in that APIs require a request to be made to receive data, while webhooks automatically send data when an event occurs without needing a request.

Right Answer:
An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. It defines the methods and data formats that applications can use to request and exchange information. APIs work by sending requests from one application to another, which then processes the request and sends back a response.

Right Answer:
API authentication is the process of verifying the identity of a user or application trying to access an API. Common methods include:

1. **API Keys**: Unique keys provided to users to access the API.
2. **Basic Authentication**: Uses a username and password encoded in Base64.
3. **OAuth**: A token-based authentication method that allows users to grant limited access to their resources without sharing credentials.
4. **JWT (JSON Web Tokens)**: A compact, URL-safe means of representing claims to be transferred between two parties, often used for stateless authentication.
5. **HMAC (Hash-based Message Authentication Code)**: Uses a secret key to create a hash of the request, ensuring data integrity and authenticity.

Right Answer:

API documentation is a technical manual that explains how to use an API, including its endpoints, request and response formats, authentication methods, and examples. It is necessary because it helps developers understand how to integrate and interact with the API effectively, ensuring proper usage and reducing errors.

AJAX (Asynchronous JavaScript and XML) is a web development technique that allows web pages to communicate with a server and update content asynchronously without reloading the entire page.

Right Answer:
Flexbox, or the Flexible Box Layout, is a CSS layout model that allows items in a container to be arranged and aligned efficiently. It works by defining a container as a flex container using `display: flex;`, which enables its direct children (flex items) to be laid out along a main axis (horizontal or vertical). You can control the alignment, direction, spacing, and size of these items using properties like `flex-direction`, `justify-content`, `align-items`, and `flex-wrap`. This makes it easier to create responsive layouts without using floats or positioning.
