---

## PASO 1: INSTALAR EVOLUTION API

### Opción A — Docker Compose (recomendado)

En tu servidor, crear el archivo `/opt/evolution-api/docker-compose.yml`:

```yaml
version: "3.7"

services:
  evolution-api:
    image: atendai/evolution-api:latest
    container_name: evolution-api
    restart: always
    ports:
      - "8080:8080"
    environment:
      - SERVER_URL=https://wa.crewinghunters.com   # subdominio que apuntes a este servidor
      - AUTHENTICATION_TYPE=apikey
      - AUTHENTICATION_API_KEY=PRISA_WA_SECRET_KEY_AQUI
      - AUTHENTICATION_EXPOSE_IN_FETCH_INSTANCES=true
      - QRCODE_LIMIT=30
      - WEBHOOK_GLOBAL_ENABLED=true
      - WEBHOOK_GLOBAL_URL=https://n8n.crewinghunters.com/webhook/prisa-whatsapp
      - WEBHOOK_EVENTS_MESSAGES_UPSERT=true
      - WEBHOOK_EVENTS_MESSAGES_UPDATE=true
      - WEBHOOK_EVENTS_CONNECTION_UPDATE=true
      - DATABASE_ENABLED=false
      - CACHE_REDIS_ENABLED=false
    volumes:
      - evolution_instances:/evolution/instances

volumes:
  evolution_instances:
```

```bash
cd /opt/evolution-api
docker-compose up -d
```

### Conectar tu número (una sola vez)

```bash
# 1. Crear instancia
curl -X POST https://wa.crewinghunters.com/instance/create \
  -H "apikey: PRISA_WA_SECRET_KEY_AQUI" \
  -H "Content-Type: application/json" \
  -d '{"instanceName": "prisa-yachts", "qrcode": true}'

# 2. Obtener QR
curl https://wa.crewinghunters.com/instance/connect/prisa-yachts \
  -H "apikey: PRISA_WA_SECRET_KEY_AQUI"
# → responde con imagen QR en base64 o URL

# 3. Escanear QR desde WhatsApp en tu teléfono
#    WhatsApp → Dispositivos Vinculados → Vincular dispositivo → Escanear QR
```

Una vez escaneado, el número queda conectado. Si el servidor se reinicia, Evolution API reconecta solo usando la sesión guardada.

---

## PASO 2: CONFIGURAR NGINX (si usas reverse proxy)

```nginx
server {
    listen 80;
    server_name wa.crewinghunters.com;
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name wa.crewinghunters.com;

    # SSL (certbot o tu certificado)
    ssl_certificate /etc/letsencrypt/live/wa.crewinghunters.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/wa.crewinghunters.com/privkey.pem;

    location / {
        proxy_pass http://localhost:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
```

---

## PASO 3: WORKFLOWS EN n8n

### Variables de entorno (agregar en n8n)

```env
PRISA_WA_API_URL=https://wa.crewinghunters.com
PRISA_WA_API_KEY=PRISA_WA_SECRET_KEY_AQUI
PRISA_WA_INSTANCE=prisa-yachts
PRISA_OWNER_PHONE=1XXXXXXXXXX   # número del dueño en formato internacional sin +
```

---

### WA-WF1: AUTO-RESPUESTA INTELIGENTE

**Trigger:** Webhook POST en `/webhook/prisa-whatsapp`

**Lógica completa:**

```
[Webhook: recibe mensaje de Evolution API]
  → [Code: extraer remoteJid, message.conversation, pushName]
  → [Code: normalizar mensaje — trim, toLowerCase]
  → [Switch — detectar intención:]

      COTIZACIÓN ("quote", "cotiz", "precio", "cost", "how much", "cuánto")
        → [HTTP: Evolution API → enviar mensaje texto]
        → [Wait 2s]
        → [HTTP: Evolution API → enviar brochure PDF]

      TECA ("teak", "teca", "wood", "madera", "deck")
        → [HTTP: Evolution API → enviar respuesta teca + brochure teca]

      ELÉCTRICO ("electric", "eléctric", "wiring", "cable", "battery", "batería", "panel")
        → [HTTP: Evolution API → enviar respuesta eléctrico + brochure eléctrico]

      UBICACIÓN ("where", "dónde", "location", "area", "stuart", "jacksonville")
        → [HTTP: Evolution API → enviar área de servicio]

      EMERGENCIA ("emergency", "urgente", "urgent", "fire", "fuego", "smoke", "humo")
        → [HTTP: Evolution API → enviar número directo]
        → [Gmail: notificar al dueño inmediatamente]

      HOLA / SALUDO (primeras palabras: "hi", "hello", "hola", "buenos", "good")
        → [HTTP: Evolution API → enviar bienvenida]

      DEFAULT (cualquier otro mensaje)
        → [HTTP: Evolution API → enviar menú de opciones]
        → [Gmail: notificar al dueño — lead sin clasificar]
```

      → [HTTP: Evolution API → enviar follow-up]
      → [Google Sheets: update status="followed_up"]
      → [Gmail: notificar al dueño]
```

## FLUJO DE IMPLEMENTACIÓN (orden)

### Semana 1: Setup
1. [ ] Instalar Evolution API con Docker en tu servidor
2. [ ] Configurar DNS: `wa.crewinghunters.com` → IP del servidor
3. [ ] Configurar Nginx + SSL (certbot)
4. [ ] Escanear QR y conectar número
5. [ ] Verificar que el webhook llega a n8n (test con mensaje de prueba)

### Semana 2: Workflows básicos
6. [ ] Construir WA-WF2 (notificación al dueño) — mínimo viable, sin riesgo
7. [ ] Construir WA-WF4 (log en Google Sheets) — solo lectura/escritura
8. [ ] Probar con mensaje real de tu propio teléfono

### Semana 3: Respuesta automática
9. [ ] Construir WA-WF1 (auto-respuesta) — empezar solo con el menú DEFAULT
10. [ ] Agregar lógica de cotización
11. [ ] Subir brochures a Google Drive, obtener FILE_IDs
12. [ ] Conectar envío de PDFs
13. [ ] Agregar resto de intenciones (teca, eléctrico, emergencia)

### Semana 4: Follow-up
14. [ ] Construir WA-WF3 (follow-up 24h)
15. [ ] Probar flujo completo end-to-end

## PREGUNTAS A RESOLVER ANTES DEL PRIMER DEPLOY

1. ¿Cuál es la IP o hostname de tu servidor?
2. ¿Ya tienes Docker instalado en el servidor?
3. ¿Usas Nginx o Caddy como reverse proxy?
4. ¿Cuál es tu número de WhatsApp (formato +1XXXXXXXXXX)?
5. ¿Tienes los brochures PDF listos o hay que crearlos primero?

---

## NOTAS IMPORTANTES

**Riesgo de ban:** WhatsApp tolera la automatización con números conectados via QR siempre que:
- Los mensajes sean respuestas a conversaciones iniciadas por el cliente (no bulk messaging)
- No envíes mensajes masivos no solicitados
- El comportamiento sea similar al humano (con delays entre mensajes)
Esta arquitectura cumple todo eso — solo responde a mensajes entrantes.

**Sesión persistente:** Evolution API guarda la sesión en el volumen Docker. Si reinicias el servidor, reconecta solo en <30 segundos sin necesidad de escanear el QR de nuevo.

**Backup del QR:** Después de conectar el número, hacer backup del volumen: `docker run --rm -v evolution_instances:/data alpine tar czf - /data > evolution_backup.tar.gz`
