n8n Event Organization Workflow with Slack, Google Calendar, and AI

This n8n workflow streamlines the process of organizing events by integrating Slack, Google Calendar, and AI capabilities. It allows you to define events in a structured format and automatically creates calendar entries and Slack reminders, leveraging AI for intelligent event summarization and scheduling.

What it does

This workflow automates the following steps:

1. Triggers on Schedule: The workflow is designed to run on a schedule (e.g., daily, weekly).
2. Filters for Specific Events: It includes a filter to process only relevant event data, likely based on certain criteria or keywords.
3. Prepares Event Data: An "Edit Fields" node (Set) is used to transform and standardize the incoming event data, ensuring it's in the correct format for subsequent nodes.
4. Generates AI-Powered Event Details: An "AI Agent" node (LangChain) is configured to interact with an "OpenAI Chat Model" and utilize "SerpApi (Google Search)" and "Wikipedia" tools. This suggests the AI agent is used to:
   • Enrich event descriptions.
   • Suggest optimal timings or locations based on search results.
   • Summarize event details for different platforms.
   • Potentially extract key information from unstructured text.
5. Parses AI Output: A "Structured Output Parser" node (LangChain) is used to extract structured information (e.g., event title, date, description) from the AI agent's output.
6. Creates Google Calendar Events: It creates new events in Google Calendar based on the processed and AI-enhanced event details.
7. Posts Slack Notifications: It sends notifications or reminders to a specified Slack channel with event details.
8. Handles Multiple Events: The "Split Out" node suggests that the workflow can process multiple event items, creating individual calendar entries and Slack messages for each.
9. Conditional Logic: An "If" node is present, indicating that certain actions might be conditional based on the AI's output or other data points, allowing for dynamic branching in the workflow.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance.
• Slack Account: Configured with an n8n Slack credential.
• Google Calendar Account: Configured with an n8n Google Calendar credential (OAuth 2.0 recommended).
• OpenAI API Key: For the OpenAI Chat Model.
• SerpApi API Key: For the SerpApi (Google Search) tool.
• Wikipedia Tool: This is a built-in LangChain tool, but ensure it's properly configured within the AI Agent.

Setup/Usage

1. Import the workflow: Download the JSON provided and import it into your n8n instance.
2. Configure Credentials:
   • Set up your Slack credential.
   • Set up your Google Calendar credential.
   • Set up your OpenAI credential.
   • Set up your SerpApi credential.
3. Customize Nodes:
   • Schedule Trigger: Adjust the schedule to your desired frequency (e.g., daily, weekly).
   • Filter: Modify the conditions in the "Filter" node to match your specific event filtering logic.
   • Edit Fields: Ensure the "Edit Fields" node correctly maps and transforms your incoming event data.
   • AI Agent: Review the prompt and tools used by the "AI Agent" to ensure it aligns with how you want the AI to process and enrich your event information.
   • Structured Output Parser: Verify the schema in the "Structured Output Parser" matches the expected output from your AI agent.
   • Google Calendar: Configure the calendar ID and event details (summary, start date, end date, description) using expressions from the previous nodes.
   • Slack: Customize the Slack channel and message content for notifications.
4. Activate the workflow: Once configured, activate the workflow to start automating your event organization.
