Automated Daily WhatsApp Group Summary Workflow

This n8n workflow automates the process of capturing, organizing, and summarizing WhatsApp group messages daily at 8 AM. It integrates Webhook triggers, Google Sheets, and OpenAI’s GPT-4 to deliver concise summaries directly to WhatsApp groups. The workflow begins with receiving messages via a webhook, then classifies the message type (text or audio). Audio messages are transcribed using OpenAI’s language model, and all messages are organized and stored in Google Sheets, segregated by groups. It checks if a group is authorized to receive summaries, retrieves relevant conversations, and generates a thematic summary using AI. The summaries are then sent back to the corresponding WhatsApp groups through an API. This setup is ideal for teams or communities wanting automated daily updates, summaries of ongoing discussions, or managed group communications with minimal manual intervention.
