This workflow enables seamless calendar management through WhatsApp using AI interpretation. When a user sends a message, the system uses OpenAI’s GPT-4 to understand the intent—whether to create, update, delete, or search for calendar events. The AI’s decision then triggers appropriate Google Calendar API actions to perform these tasks automatically. The setup also includes memory buffers and confirmation messages sent back via WhatsApp, making it a robust virtual assistant for scheduling. Practical use cases include scheduling meetings, checking availability, or managing events hands-free, ideal for busy professionals seeking instant calendar control through conversational messaging.
