What the standard connections between B2C Commerce, a third-party OMS, Order Management, the service org, Marketing Cloud Engagement, Personalization, Loyalty Management and Data 360 do out of the box, where their documented limits sit, and when a requirement needs a custom integration instead.

- Certification: Salesforce B2C Solution Architect
- Exam section: Integration
- Study guide: https://www.certifyforce.com/study-guide/b2c-solution-architect

**Official exam objective:**

> Given a set of customer requirements, recommend an appropriate design and approach for a multi-product integration, understanding the OOTB features, system limitations, and when custom integration is required.

## What the exam expects

- Configure the B2C Commerce order export for a third-party OMS, and know what order import can't do.
- Protect inventory and price feeds from oversell and orphan cleanup with standard settings.
- Size Email-to-Case and Web-to-Case against their limits, and spot when an API integration is needed.
- Pick the Marketing Cloud Connect feature for a service-to-marketing requirement.
- Judge when Loyalty business APIs, Personalization open time email or the Data 360 Engagement connector fit.

Key terms:
- **Third-party OMS:** an external order management system fed by the XML order export.
- **On Order Inventory:** an inventory-list option that holds an on-order amount for orders not yet exported.
- **Marketing Cloud Connect:** the connector between Marketing Cloud Engagement and a Salesforce org.
- **Synchronized Data Sources:** the Connect feature that copies Salesforce objects into synchronized data extensions.
- **Open time email campaign:** a Marketing Cloud Personalization (formerly Interaction Studio) campaign that picks content when the email opens.
