What is a webhook in the context of Salesforce Commerce Cloud?

A webhook in the context of Salesforce Commerce Cloud (SFCC) is defined as an HTTP callback that triggers an event or action. This mechanism allows for real-time communication between different systems. When a specified event occurs in one system (such as a purchase made or an inventory updated), a webhook sends an HTTP request to a specified URL, which can then handle that event appropriately, often triggering further processes, workflows, or notifications in another system.

This functionality is crucial for enabling integrations and automated responses across applications without requiring constant polling or checks. Instead, when the event of interest happens, the webhook efficiently sends the information directly, allowing for a more responsive and streamlined architecture.

The options pertaining to API interfaces for database management, server performance optimization, and user session management do not accurately describe what a webhook is or does within SFCC. While those topics are relevant in the context of commerce platforms, they do not relate to the specific function of webhooks, which focuses on enabling event-driven interactions between systems.
