How B2C Commerce, Marketing Cloud Engagement, Order Management, Omnichannel Inventory and the service org hand data to each other in a consumer journey: the abandoned-cart reference implementation and its feeds, reservation and fulfillment-order handoffs, order cases in the Service Console and the B2C CRM Sync profile flow.

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

**Official exam objective:**

> Given the understanding of retail solution architecture and integrations, illustrate how Salesforce products interact with each other and third-party systems to support consumer commerce journeys.

## What the exam expects

- Assign who authors, triggers and delivers messages in the Commerce-to-Engagement abandoned-cart reference implementation.
- Choose a catalog feed pattern and adapt the feed model for languages, currencies, brands and inventory.
- Describe the customer-built contract that turns an email link into a rebuilt cart.
- Trace an Omnichannel Inventory reservation and a fulfillment order from routing to shipment.
- Explain order cases in the Service Console and the B2C CRM Sync profile flow.

Key terms:
- **Reference implementation:** a developer enablement framework of code, configuration and patterns that still needs customization.
- **collect.js:** Engagement's storefront tracking code for shopper behavior.
- **Location group:** an Omnichannel Inventory aggregate whose availability is the sum of its locations.
- **Fulfillment order:** the record that assigns order items to one fulfilled-from location.
- **B2C CRM Sync:** Salesforce's open enablement solution that synchronizes Commerce profiles with Salesforce Accounts and Contacts or Person Accounts.
