How to use LWC & Platform Event with MuleSoft?

 

Hello #Trailblazer #Mules,

In this blog post we are going to talk The Power of MuleSoft + LWC with Platform Event

Scenario

SFDCPanther is the whole seller of the parts of the heavy vehicles and the customer can reach out to Sales Rep to check if they are eligible for a discount or not.

Key points to Remember

1. Sales Rep will be in Salesforce System
2. Discount Details are available in a different Database
3. The customer will be sitting on the Salesforce Digital Experience Site
4. Sales Reps must need an Interface where they can enter Customer Identifier and Location to check the discount availability.
5. SFDCPanther is concern about the security while making the call to an external database

Solution

The Salesforce Architect at SFDCPanther suggested using MuleSoft & Platform Event along with the LWC Component to achieve the solution.

Solution Approach

1. Use JWT to connect with MuleSoft
2. Create 2 Platform Event one for Making a call to External System using MuleSoft and the other for Salesforce to listen to the response from MuleSoft
3. Create a Lightning Web Component to have the required input
4. Publish the Platform Event using LWC
5. Listen to the same event in MuleSoft, then make a Query to the database and publish the event from MuleSoft
6. LWC will listen to the Event and display the message
7. Test It
