Module 2 — Building a Real Mule Flow

We’ll build this:

POST /customers
      ↓
HTTP Listener
      ↓
Validate / preserve request
      ↓
Transform JSON → Salesforce Account
      ↓
Salesforce Upsert
      ↓
Transform Salesforce result → API response
      ↓
HTTP 200/201

This is a very typical MuleSoft pattern. MuleSoft’s own Salesforce examples use essentially the same sequence: HTTP Listener → Transform Message → Salesforce operation → Transform Message.
