## Common API Operations

### 1. List All Workflows

```bash
curl -X GET "http://localhost:8098/api/v1/workflows" \
  -H "X-N8N-API-KEY: n8n_api_42f1838c1e2de90cadcb669f78083de92697a85322c0b6009ad2e55760db992ab0bf61515a3cf0e1" \
  -H "Accept: application/json"
```

**Response Fields:**
- `id` - Workflow ID (use for updates/deletes)
- `name` - Workflow name
- `active` - true/false (is workflow enabled?)
- `nodes` - Array of workflow nodes
- `connections` - Node connections map

**Current Workflows (as of Nov 26, 2025):**
- `gUDqTiHyHSfRUXv6` - **Money Machine** (Active: true) - Main trading workflow
- `Zk4gbBzjxVppHiCB` - nextcloud deck tf bank (Active: true)

  -H "Content-Type: application/json" \
  -d '{"active": false}'
```

### 5. Execute Workflow

```bash
curl -X POST "https://flow.egonetix.de/api/v1/workflows/{workflow_id}/executions" \
  -H "X-N8N-API-KEY: n8n_api_42f1838c1e2de90cadcb669f78083de92697a85322c0b6009ad2e55760db992ab0bf61515a3cf0e1" \

## Trading Bot Workflows

### Key Workflows to Manage

1. **Parse Signal Enhanced**
   - Extracts metrics from TradingView alerts
   - Parses: ATR, ADX, RSI, volumeRatio, pricePosition, timeframe, indicator version
   - **Future:** Will include maGap for v9 indicator

2. **Check Risk**
   - Calls `/api/trading/check-risk` endpoint
   - Validates signal quality score
   - Checks duplicate signals, cooldown periods
   - Blocks if quality < threshold (LONG: 90, SHORT: 95)

3. **Execute Trade**
   - Calls `/api/trading/execute` endpoint
   - Opens position on Drift Protocol
   - Places TP/SL orders
   - Adds to Position Manager monitoring

### Updating Workflows for v9 Enhancement

When implementing v9 MA gap enhancement:

**Step 1: Update Parse Signal Enhanced node**
```json
{
  "nodes": [
    {
      "name": "Parse Signal Enhanced",
      "parameters": {
        "jsCode": "// Add MA gap parsing\nconst maGapMatch = message.match(/MAGAP:([\\d.-]+)/);\nconst maGap = maGapMatch ? parseFloat(maGapMatch[1]) : undefined;\n\nreturn { maGap };"
      }
    }
  ]
}
```

**Step 2: Update HTTP Request nodes**
Add `maGap` to request body:
```json
{
  "body": {
    "symbol": "={{$json.symbol}}",
    "direction": "={{$json.direction}}",
    "atr": "={{$json.atr}}",
    "adx": "={{$json.adx}}",
    "rsi": "={{$json.rsi}}",
    "volumeRatio": "={{$json.volumeRatio}}",
    "pricePosition": "={{$json.pricePosition}}",
    "maGap": "={{$json.maGap}}",
    "timeframe": "={{$json.timeframe}}"
  }
}
```

## Workflow IDs Reference

**Trading Workflow:**
- **ID:** `gUDqTiHyHSfRUXv6`
- **Name:** Money Machine
- **Status:** Active
- **Nodes:**
  - Parse Signal Enhanced (extracts TradingView metrics)
  - Check Risk1 (validates quality score, duplicates, cooldowns)
  - Execute Trade1 (opens position on Drift)
  - Trade Success? (validation branching)

**Quick Commands:**
```bash
# Get Money Machine workflow

## Troubleshooting

### API Connection Issues

**DNS Resolution Failed:**
```bash
# Test DNS
ping flow.egonetix.de

# If fails, check:
# 1. n8n instance is running
# 2. Domain DNS is configured
# 3. Server firewall allows access
```

**SSL Certificate Issues:**
```bash
# Test with --insecure (dev only!)
curl --insecure -X GET "https://flow.egonetix.de/api/v1/workflows" \
  -H "X-N8N-API-KEY: n8n_api_42f1838c1e2de90cadcb669f78083de92697a85322c0b6009ad2e55760db992ab0bf61515a3cf0e1"
```

**401 Unauthorized:**
- Verify API key is correct (no typos)
- Check API key hasn't been revoked in n8n settings
- Ensure API access is enabled in n8n instance

---

## Security Best Practices

1. **Store API key in .env file** (never commit to git)
2. **Use environment variables** in scripts:
   ```bash
   export N8N_API_KEY="n8n_api_42f1838c1e2de90cadcb669f78083de92697a85322c0b6009ad2e55760db992ab0bf61515a3cf0e1"
   curl -H "X-N8N-API-KEY: $N8N_API_KEY" ...
   ```
3. **Rotate API keys periodically** (quarterly recommended)
4. **Monitor API usage** in n8n admin panel
5. **Restrict API key permissions** if possible (read vs write)

## Automated Workflow Management Scripts

### Check Workflow Status
```bash
#!/bin/bash
# check-n8n-workflows.sh

API_KEY="n8n_api_42f1838c1e2de90cadcb669f78083de92697a85322c0b6009ad2e55760db992ab0bf61515a3cf0e1"
BASE_URL="https://flow.egonetix.de/api/v1"

echo "🔍 Checking n8n workflows..."
curl -s -X GET "$BASE_URL/workflows" \
  -H "X-N8N-API-KEY: $API_KEY" \
  | jq -r '.data[] | "[\(if .active then "✅" else "❌" end)] \(.name) (ID: \(.id))"'
```

### Deploy Workflow Update
```bash
#!/bin/bash
# deploy-workflow-update.sh

WORKFLOW_ID=$1
WORKFLOW_FILE=$2

if [ -z "$WORKFLOW_ID" ] || [ -z "$WORKFLOW_FILE" ]; then
  echo "Usage: ./deploy-workflow-update.sh <workflow_id> <workflow.json>"
  exit 1
fi

API_KEY="n8n_api_42f1838c1e2de90cadcb669f78083de92697a85322c0b6009ad2e55760db992ab0bf61515a3cf0e1"
BASE_URL="https://flow.egonetix.de/api/v1"

echo "📤 Deploying workflow update..."
curl -X PATCH "$BASE_URL/workflows/$WORKFLOW_ID" \
  -H "X-N8N-API-KEY: $API_KEY" \
  -H "Content-Type: application/json" \
  -d @"$WORKFLOW_FILE" \
  | jq '.'
```

## Next Steps After API Test

Once n8n instance is reachable:

1. **Test API connection:**
   ```bash
   curl -X GET "https://flow.egonetix.de/api/v1/workflows" \
     -H "X-N8N-API-KEY: n8n_api_42f1838c1e2de90cadcb669f78083de92697a85322c0b6009ad2e55760db992ab0bf61515a3cf0e1"
   ```

2. **Document workflow IDs** in this file

3. **Update .env file** with API key:
   ```bash
   sed -i 's/N8N_API_KEY=.*/N8N_API_KEY=n8n_api_42f1838c1e2de90cadcb669f78083de92697a85322c0b6009ad2e55760db992ab0bf61515a3cf0e1/' /home/icke/traderv4/.env
   ```

4. **Backup current workflows:**
   ```bash
   mkdir -p /home/icke/traderv4/workflows/n8n/backups
   # Export each workflow via API
   ```

5. **Test workflow update** with non-critical workflow first
