n8n Workflow: Event RSVP Lead Scoring with GPT-4o Mini, HubSpot Sync, and Slack Alerts

This n8n workflow automates the process of lead scoring for event RSVPs, leveraging AI for sentiment analysis, syncing data with HubSpot, and providing real-time alerts on Slack. It's designed to help event organizers quickly identify and prioritize high-value leads based on their responses.

What it does

This workflow streamlines the management of event RSVPs through the following steps:

  1. Triggers on new RSVP data: Listens for incoming event RSVP data, likely from a form submission or an external system, via a Webhook.
  2. Analyzes RSVP responses with AI: Processes the RSVP data using an OpenAI node to perform sentiment analysis or extract key information, likely to generate a lead score or categorization.
  3. Transforms and Prepares Data: Uses an "Edit Fields (Set)" node to structure and format the data for subsequent actions, ensuring consistency before syncing or alerting.
  4. Conditional Processing: Routes the processed RSVP data based on a condition defined in an "If" node. This could be used to differentiate between high-priority and low-priority leads, or specific response types.
  5. Syncs with Google Sheets: For all incoming RSVP data, it adds a new row to a specified Google Sheet, ensuring a centralized record of all responses.
  6. Updates HubSpot (Conditional): If the conditional check passes (e.g., a high lead score), the workflow creates or updates a contact in HubSpot with the relevant RSVP details and AI-generated insights.
  7. Sends Slack Alerts (Conditional): If the conditional check passes, it sends a notification to a designated Slack channel, alerting the team about a high-priority RSVP.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running instance of n8n.
  • Webhook Endpoint: An external system configured to send RSVP data to the n8n Webhook.
  • OpenAI API Key: For the OpenAI node to perform AI-driven analysis.
  • Google Account: With access to Google Sheets for storing RSVP data.
  • HubSpot Account: For CRM synchronization.
  • Slack Account: For receiving real-time alerts.

Setup/Usage

  1. Import the Workflow: Download the JSON provided and import it into your n8n instance.
  2. Configure Credentials:
    • OpenAI: Set up your OpenAI API key credential.
    • Google Sheets: Connect your Google account for Google Sheets.
    • HubSpot: Connect your HubSpot account.
    • Slack: Connect your Slack workspace.
  3. Configure Nodes:
    • Webhook: The URL for this webhook will be generated once the workflow is activated. Configure your external RSVP system to send data to this URL.
    • OpenAI: Review and adjust the prompt for the AI model (e.g., GPT-4o Mini) to accurately analyze your RSVP responses and generate the desired output (e.g., lead score, sentiment).
    • Edit Fields (Set): Map the incoming data from the webhook and the output from OpenAI to the desired fields for HubSpot, Google Sheets, and Slack.
    • If: Define the conditions for routing. For example, {{ $json.leadScore > 70 }} to identify high-priority leads.
    • Google Sheets: Specify the Google Sheet ID and the sheet name where RSVP data should be appended.
    • HubSpot: Configure the "Create or Update Contact" operation, mapping the relevant fields from the workflow to HubSpot contact properties.
    • Slack: Specify the Slack channel and customize the message content for alerts.
  4. Activate the Workflow: Once all configurations are complete, activate the workflow.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
