WhatsApp Message Echo Workflow with Webhook Verification

This n8n workflow is designed to create a simple WhatsApp chatbot that echoes received messages back to the sender while ensuring webhook verification with Meta. The flow begins with a webhook for verification, where it handles GET requests from Facebook for webhook setup. Once verified, the same webhook listens for POST requests carrying WhatsApp messages. When a message is received, the workflow checks if the incoming data contains a message and responds by echoing the exact message back to the sender via WhatsApp. Sticky notes are used throughout to explain setup steps and important configurations, making this workflow ideal for developers setting up WhatsApp integrations for customer support or interactive chatbots.
