How do you create a new custom endpoint in Salesforce B2C Commerce?

Creating a new custom endpoint in Salesforce B2C Commerce is accomplished by implementing a controller in a cartridge. In Salesforce B2C Commerce, a controller is a key component that processes incoming requests and generates responses.

When you implement a controller, you can define custom logic for handling specific API calls or web requests. This involves defining routes in the controller and specifying how to handle the incoming data, process it, and return the appropriate responses. The flexibility of controllers allows developers to build custom functionality tailored to business requirements, such as integrating with third-party services, private APIs, or unique application logic.

Controllers live within a cartridge, which serves as a package containing all elements related to a specific functionality within the platform. Therefore, as you create a controller within a cartridge, it acts as your custom endpoint for your Salesforce B2C Commerce storefront, facilitating the required data processing and responses.

Other choices may relate to various parts of the platform but do not directly pertain to the creation of a custom endpoint as effectively as implementing a controller in a cartridge.
