This tutorial provides a step-by-step guide on how to integrate Salesforce with WhatsApp using Twilio. The integration allows businesses to communicate directly with customers through WhatsApp, providing personalized messages, quick updates, and streamlined workflows within the Salesforce platform. To complete this integration, users need to set up their Twilio account, install the necessary software and plugins in Visual Studio Code (VS Code), create a Salesforce Developer account, and configure their Apex class using the Twilio WhatsApp API. The integration also requires deploying the Lightning Web Component (LWC) and Apex Class to the Source Org in VS Code. Once deployed, users can test the functionality by sending messages from their WhatsApp number to the Twilio WhatsApp Sandbox number, which will then be sent as a message within the Salesforce platform.
