Assemble Customer Profile for Process API
In this challenge you assemble a standardized customer profile object from two sources: the registration payload arriving from the web storefront, and two flow variables carrying channel and region context set earlier in the flow. The Transform Message sits inside a Process API layer and forwards the assembled object to the Salesforce System API. You will practice the most fundamental DataWeave pattern: constructing a single output object from fields drawn across multiple Mule message sources.
