This document outlines a use case for integrating Mulesoft with Salesforce to update a Salesforce object using a JSON payload via an HTTP endpoint. It details the steps to configure connectors, metadata, a message enricher, and the transformation of JSON data, ultimately guiding the user on how to update a specific contact's department in Salesforce. It provides an example JSON for updating a contact's last name and department, and concludes with instructions on testing the flow with a POST request.
