When a guest submits an enquiry via webhook, an AI agent analyzes the message to detect intent (booking, pricing, availability, or policy), generates a personalized acknowledgment, and routes the enquiry to the appropriate team with SLA tracking. If the guest prefers email contact, an automated reply is sent. All enquiries are logged to Slack with full context for team follow-up.\n\n### Setup steps\n1. Configure the webhook URL in your booking form\n2. Connect Gmail OAuth2 credentials for email replies\n3. Add Slack workspace credentials for internal notifications\n4. Connect OpenAI API key for AI classification\n5. Update agent email addresses in assignment nodes\n6. Test with a sample enquiry to verify routing"
