9.39An interview scenario

We have Salesforce, SAP, and a billing platform. Mobile and web both need a unified customer view. How would you structure it?

Good answer:

Mobile Experience API
Web Experience API
        ↓
Customer Profile Process API
        ↓
 ┌──────┼───────┐
 ↓      ↓       ↓
Salesforce SAP Billing
System API API API

Then explain:

“The System APIs isolate backend-specific connectors, schemas, and authentication. The Process API orchestrates and normalizes the unified customer view. Experience APIs adapt that view where mobile and web contracts genuinely differ.”

Excellent.
