What is the B2C Commerce API used for?
Real World Scenario
Shoppers browse products on a custom site. You explain which Salesforce API powers product and cart data.
Expected Answer
• B2C Commerce APIs expose catalog, basket, checkout, and customer operations to external apps
• Shopper-facing sites call these APIs instead of Salesforce storefront templates
• APIs handle sessions, pricing, promotions, and inventory from the commerce backend
• Authentication ties shoppers to registered profiles when logged in
• Rate limits and API versions must be tracked like any Salesforce integration

Commerce APIs are purpose-built for storefront flows with optimized endpoints. Custom Apex REST is flexible but you rebuild commerce patterns yourself.
Architect Perspective
Know the happy path: browse → basket → checkout → order. APIs map to that story.
