Reemplaza los 4 placeholders\n\nUsa Ctrl+F en el workflow y reemplaza:\n\n- `REEMPLAZA_TU_META_PIXEL_ID` → tu Pixel ID (Events Manager)\n- `REEMPLAZA_TU_META_ACCESS_TOKEN` → token CAPI permanente\n- `REEMPLAZA_TU_GA4_MEASUREMENT_ID` → G-XXXXXXXXXX\n- `REEMPLAZA_TU_GA4_API_SECRET` → Admin > Data Streams > Measurement Protocol API secrets\n\n## 2. (Opcional) Ajusta el evento\n\nEn el Code Node \"Prepare Tracking Data\":\n\n- `EVENT_NAME_META` default: Lead (otros: Schedule, Purchase, CompleteRegistration)\n- `EVENT_NAME_GA4` default: generate_lead (snake_case GA4 recommended events)\n- `EVENT_VALUE` default: 0\n- `EVENT_CURRENCY` default: CLP\n\n## 3. Activa el workflow\n\nToggle \"Active\" arriba a la derecha. Copia la **Production URL** del Webhook Trigger.\n\n## 4. Conecta con Clinera\n\nEn Clinera > Automatizaciones, crea un trigger (ej: \"Cambio de etapa de contacto a Lead\")\ncon accion HTTP POST a la URL del webhook. Payload sugerido:\n\n```json\n{\n \"contacto\": { \"id\": \"123\", \"email\": \"...\", \"telefono\": \"+56...\", \"nombre\": \"...\", \"apellido\": \"...\" },\n \"fbp\": \"...\", \"fbc\": \"...\",\n \"event_id\": \"...\",\n \"utm_campaign\": \"...\"\n}\n```\n\nEl workflow acepta payload con o sin wrapper `body`.\n\n## 5. Valida\n\n- **Meta**: Events Manager > Test Events (manda 1 evento real)\n- **GA4**: Configurar > DebugView (anade `debug_mode: true` al payload si quieres)\n\nDocs oficiales:\n- Meta CAPI: https://developers.facebook.com/docs/marketing-api/conversions-api\n- GA4 MP: https://developers.google.com/analytics/devguides/collection/protocol/ga4\n", "height": 620, "width": 520, "color": 4 }, "id": "f1a2b3c4-0001-4001-8001-000000000001", "name": "Instrucciones", "type": "n8n-nodes-base.stickyNote", "typeVersion": 1, "position": [ -1480, -360 ] }, { "parameters": { "httpMethod": "POST", "path": "clinera-tracking", "responseMode": "responseNode", "options": {} }, "id": "f1a2b3c4-0002-4002-8002-000000000002", "name": "Webhook Trigger", "type": "n8n-nodes-base.webhook", "typeVersion": 2.1, "position": [ -1040, 280 ], "webhookId": "clinera-tracking" }, { "parameters": { "jsCode": "// ================================================================\n// CODE NODE — Prepare Tracking Data\n// Workflow: Clinera | Tracking Meta CAPI + GA4\n//\n// Recibe payload de Clinera (con o sin wrapper \"body\") y prepara:\n// 1.
