It is designed for ticketing platforms, event operators, and venue operations teams that must prevent fraud, manage inventory accurately, and deliver seamless customer communication at scale. The workflow solves key challenges such as duplicate bookings, bot-driven purchases, payment failures, overbooking, and inconsistent refund handling. When a booking request enters via webhook, inventory data is fetched and normalized. The Ticket Validation Agent analyzes structured booking, payment authorization, pricing tier rules, seat allocation, resale restrictions, and fraud signals to produce a standardized risk classification. Based on risk level, the workflow routes transactions for auto-approval, conditional handling, or escalation. The Fan Experience Orchestration Agent then manages confirmations, ticket system updates, waitlist activation, refund or compensation logic, and SLA-driven escalation to operations. All outcomes are merged and logged into an audit trail, ensuring compliance, transparency, and consistent service enforcement while minimizing manual review." }, "typeVersion": 1 }, { "id": "191b9b91-04e3-4c52-807c-fe5b5e52cc56", "name": "Sticky Note3", "type": "n8n-nodes-base.stickyNote", "position": [ -1728, 96 ], "parameters": { "color": 7, "width": 1264, "height": 544, "content": "## Ingest & Ticket Validation\n**What** \u2013 AI verifies payment, fraud signals, tier rules.\n**Why** \u2013 Prevent invalid or high-risk transactions." }, "typeVersion": 1 }, { "id": "842d5cf5-07fa-4c39-957b-2627120649bf", "name": "Sticky Note4", "type": "n8n-nodes-base.stickyNote", "position": [ -112, 80 ], "parameters": { "color": 7, "width": 512, "height": 560, "content": "## Fan Orchestration\n**What** \u2013 Confirm, reschedule, refund, escalate.\n**Why** \u2013 Enforce SLAs and protect fan experience." }, "typeVersion": 1 }, { "id": "d0a32c5a-f567-4c38-9139-9eafaf015bfb", "name": "Sticky Note5", "type": "n8n-nodes-base.stickyNote", "position": [ -448, 80 ], "parameters": { "color": 7, "width": 320, "height": 576, "content": "## Risk Routing\n**What** \u2013 Route by low, medium, or high risk.\n**Why** \u2013 Focus human review only where necessary." }, "typeVersion": 1 }, { "id": "8a4ce6a5-94f7-469c-93a2-9eba69ce60d7", "name": "Sticky Note6", "type": "n8n-nodes-base.stickyNote", "position": [ 416, 64 ], "parameters": { "color": 7, "width": 720, "height": 576, "content": "## Audit Logging\n**What** \u2013 Merge paths and log outcomes.\n**Why** \u2013 Maintain compliance and traceability." }, "typeVersion": 1 } ], "active": false, "settings": { "availableInMCP": false, "executionOrder": "v1" }, "versionId": "08f7ef11-610e-447d-8fdf-691ee90671b6", "connections": { "Merge All Paths": { "main": [ [ { "node": "Log to Audit Trail", "type": "main", "index": 0 } ] ] }, "Route by Risk Level": { "main": [ [ { "node": "Fan Experience Orchestration Agent", "type": "main", "index": 0 } ], [ { "node": "Alert Operations Team", "type": "main", "index": 0 } ] ] }, "Fetch Inventory Data": { "main": [ [ { "node": "Prepare Validation Input", "type": "main", "index": 0 } ] ] }, "Alert Operations Team": { "main": [ [ { "node": "Merge All Paths", "type": "main", "index": 1 } ] ] }, "Ticket Booking Webhook": { "main": [ [ { "node": "Workflow Configuration", "type": "main", "index": 0 } ] ] }, "Workflow Configuration": { "main": [ [ { "node": "Fetch Inventory Data", "type": "main", "index": 0 } ] ] }, "Send Confirmation Email": { "main": [ [ { "node": "Merge All Paths", "type": "main", "index": 0 } ] ] }, "Ticket Validation Agent": { "main": [ [ { "node": "Route by Risk Level", "type": "main", "index": 0 } ] ] }, "Update Ticketing System": { "main": [ [ { "node": "Send Confirmation Email", "type": "main", "index": 0 } ] ] }, "Prepare Validation Input": { "main": [ [ { "node": "Ticket Validation Agent", "type": "main", "index": 0 } ] ] }, "Validation Output Parser": { "ai_outputParser": [ [ { "node": "Ticket Validation Agent", "type": "ai_outputParser", "index": 0 } ] ] }, "OpenAI Model - Validation": { "ai_languageModel": [ [ { "node": "Ticket Validation Agent", "type": "ai_languageModel", "index": 0 } ] ] }, "Orchestration Output Parser": { "ai_outputParser": [ [ { "node": "Fan Experience Orchestration Agent", "type": "ai_outputParser", "index": 0 } ] ] }, "OpenAI Model - Orchestration": { "ai_languageModel": [ [ { "node": "Fan Experience Orchestration Agent", "type": "ai_languageModel", "index": 0 } ] ] }, "Fan Experience Orchestration Agent": { "main": [ [ { "node": "Update Ticketing System", "type": "main", "index": 0 } ] ] } } }
