This n8n workflow seamlessly integrates AI chat capabilities with Google Calendar, enabling dynamic event management via WhatsApp interactions. It starts with triggering on WhatsApp messages or external workflow executions, then uses AI agents and language models to process natural language input. The workflow can retrieve, create, update, or delete calendar events based on user commands, with context maintained using memory buffers. It also delivers automated responses via WhatsApp, creating an interactive and intelligent scheduling assistant. Practical for automating appointment handling, reminders, or user queries through conversational AI.
