What type of data format is commonly used in webhooks for transmitting information?

The commonly used data format in webhooks for transmitting information is JSON (JavaScript Object Notation). JSON is favored for several reasons, making it the preferred choice in many modern applications and APIs.

Firstly, JSON is lightweight, which allows for efficient data transmission over the internet. Its structure is easy to read and write for humans and easily parsed by machines. This makes it ideal for webhooks, which are designed to send notifications and data asynchronously over HTTP when a specific event occurs.

Secondly, JSON supports complex data structures, including hierarchical data, which is often necessary when transmitting detailed information. This flexibility allows developers to include arrays and nested objects, accommodating a wide array of use cases in more complex applications.

Furthermore, many web services and APIs, especially those that interact with JavaScript, natively support JSON, allowing for smooth integration and interoperability without the need for additional parsing tools or libraries.

In contrast, while XML is another option for data interchange, it tends to be more verbose and complex compared to JSON. CSV is primarily used for tabular data, making it less suitable for hierarchical or nested structures that webhooks might require. HTML is a markup language primarily intended for structuring content on the web, not for data interchange.

Thus, given these factors
