Criar e gerir webhooks para receber dados externos.

---

## Uso

```
/n8n-webhook create <descrição>    # Criar novo webhook
/n8n-webhook list                  # Listar webhooks existentes
/n8n-webhook test <workflow_id>    # Testar webhook
```

---

## Workflow Obrigatório

```
1. Health check       → mcp__n8n__n8n_health_check()
2. Pesquisar template → mcp__n8n__search_templates({ query: "webhook" })
3. Se template OK     → mcp__n8n__n8n_deploy_template()
4. Se criar do zero   → Seguir fluxo abaixo
```

## Criar Webhook do Zero

### Passo 1: Documentação do Node

```javascript
mcp__n8n__get_node({
  nodeType: "nodes-base.webhook",
  detail: "standard",
  includeExamples: true
})
```

### Passo 2: Validar Configuração

```javascript
mcp__n8n__validate_node({
  nodeType: "nodes-base.webhook",
  config: {
    httpMethod: "POST",
    path: "meu-webhook",
    responseMode: "onReceived"
  },
  mode: "minimal"
})
```

### Passo 3: Nodes de Processamento

| Node | Uso |
|------|-----|
| `nodes-base.set` | Transformar dados |
| `nodes-base.if` | Condicionais |
| `nodes-base.code` | JavaScript custom |
| `nodes-base.httpRequest` | Chamar APIs |

### Passo 4: Deploy

```javascript
mcp__n8n__n8n_create_workflow({
  name: "Webhook - Descrição",
  nodes: [...],
  connections: {...},
  active: true
})
```

| `authentication` | none, basicAuth, headerAuth | none |
| `responseMode` | onReceived, lastNode | onReceived |

## URL do Webhook

Após deploy:
```

```

Modo teste (workflow inactivo):
```
https://automator.descomplicar.pt/webhook-test/<path>
```

---

## Exemplos

### Webhook → Slack

```
Webhook (POST /notify)
  ↓
Set (formatar)

Slack (enviar)
```

### Webhook → CRM

```
Webhook (POST /lead)
  ↓
HTTP Request (criar no Desk)
  ↓
Email (notificar)
```

## Testar

```javascript
mcp__n8n__n8n_test_workflow({
  workflowId: "wf-xxx",
  inputData: {
    body: { "test": "data" },
    headers: { "Content-Type": "application/json" }
  }
})
```

```bash
curl -X POST https://automator.descomplicar.pt/webhook/meu-webhook \
  -H "Content-Type: application/json" \
  -d '{"test": "data"}'
```

---

## Troubleshooting

| Problema | Solução |
|----------|---------|
| 404 Not Found | Workflow não está activo |
| 401 Unauthorized | Verificar autenticação |
| Dados não chegam | Verificar responseMode |
