Automated Slack Event Creation & Attendee Management Workflow

This n8n workflow streamlines the process of managing events directly from Slack, integrating with Google Calendar and leveraging AI to enhance automation. It begins by monitoring a designated Slack channel for messages tagged with a calendar emoji 📅, indicating a request to create a new event. When such a message is detected, the workflow uses an AI-powered agent to analyze and parse the message, generating an engaging event title, extracting dates, times, and location details, and classifying the event type.

If a new event is to be created, the system gathers all relevant information and automatically schedules the event in Google Calendar, including details like event title, description, location, and attendee permissions. For existing events, the workflow checks for user reactions (✅ emoji), interpreting them as attendee confirmations. It then fetches the current event details and updates the attendee list in Google Calendar accordingly.

The workflow includes multiple steps such as Slack message parsing, API calls to SerpAPI for location data, OpenAI and LangChain agents for natural language processing, and Google Calendar for event management. It supports scenarios like automated event scheduling, attendee updates based on reactions, and seamless communication in Slack.

This automation is particularly useful for teams or communities that frequently organize meetings or events via Slack, enabling real-time, AI-assisted event creation, and dynamic attendee management without manual intervention.
