The B2C Commerce to Service Cloud Connector is a solution that enables integration between B2C Commerce and Service Cloud. It allows displaying customer and order information in Service Cloud, creating orders on behalf of customers, and synchronizing customer data between the two systems. When introducing the Service Cloud Connector into an existing Salesforce Org, the following functionality considerations should be aware of:
In order to implement the Service Cloud Connector it is necessary to enable Person Accounts, a change which cannot be reverted once implemented. Person Accounts are a type of account in Salesforce that combines an account and a contact into a single record. The Service Cloud Connector requires Person Accounts to store customer information from B2C Commerce. Enabling Person Accounts is an irreversible change that affects the entire Salesforce Org and may have implications for other features or customizations.
The Service Cloud Connector is distributed as a managed package that can be extended to meet client-specific needs but with core functionality that cannot be altered. A managed package is a collection of application components that can be installed from AppExchange or other sources. The Service Cloud Connector is a managed package that provides core functionality for integrating B2C Commerce and Service Cloud. The core functionality cannot be modified or deleted, but it can be extended or customized using Apex code, Visualforce pages, or Lightning components.
Option C is incorrect because the Service Cloud Connector does not natively support accounts and contacts, households, and multi-brand customer models. It only supports person accounts as a customer model by default. Option D is incorrect because the Service Cloud Connector provides a collection of Lightning components that display customer and order information within Service Cloud, which do not need to be customized or deployed by a developer.
