## Technical Implementation

### Environment Variables
```bash
N8N_BASE_URL="https://your-n8n-instance.com"
N8N_API_KEY="your-api-key"
```

### Budget Validation (Enforced)
All budget operations validate against limits:

```bash
DAILY_MAX=500
LIFETIME_MAX=5000

if (( $(echo "$DAILY_BUDGET > $DAILY_MAX" | bc -l) )); then
  echo '{"error": "Daily budget exceeds maximum ($500)", "code": "BUDGET_EXCEEDED"}' >&2
  exit 3
fi
```

### Exit Codes
- `0`: Success
- `1`: Validation error (invalid parameters)
- `2`: API error (network/platform failure)
- `3`: Budget violation

### Error Response Format
```json
{
  "error": "Error description",
  "code": "ERROR_CODE",
  "details": {
    "field": "field_name",
    "constraint": "constraint_description"
  }
}
```

## Integration Example

```bash
#!/bin/bash
# Create campaign and monitor performance

CAMPAIGN_ID=$(
  ./.claude/skills/cfn-marketing-ad-campaigns/operations/create-campaign.sh \
    --platform google_ads \
    --campaign-name "Black Friday Sale" \
    --daily-budget 250 \
    --lifetime-budget 5000 \
    --target-audience '{"age":"25-54","interests":["shopping","deals"]}' \
    --bid-strategy maximize_conversions | jq -r '.campaign_id'
)

echo "Campaign created: $CAMPAIGN_ID"

# Wait 7 days
sleep 604800

# Check performance
./.claude/skills/cfn-marketing-ad-campaigns/operations/get-campaign-performance.sh \
  --campaign-id "$CAMPAIGN_ID" \
  --date-range last_7_days

# Adjust budget if performing well
ROAS=$(get-campaign-performance.sh --campaign-id "$CAMPAIGN_ID" | jq -r '.metrics.roas')

if (( $(echo "$ROAS > 4.0" | bc -l) )); then
  echo "Strong performance, increasing budget"
  ./.claude/skills/cfn-marketing-ad-campaigns/operations/set-budget.sh \
    --campaign-id "$CAMPAIGN_ID" \
    --daily-budget 350
fi
```

## Testing

### Mock Data Setup
```bash
# Set test environment
export N8N_BASE_URL="http://localhost:5678"
export N8N_API_KEY="test-key-12345"

# Test campaign creation
./.claude/skills/cfn-marketing-ad-campaigns/operations/create-campaign.sh \
  --platform google_ads \
  --campaign-name "Test Campaign" \
  --daily-budget 50 \
  --lifetime-budget 500 \
  --target-audience '{"test":true}'
```

### Budget Validation Tests
```bash
# Test daily budget violation
./.claude/skills/cfn-marketing-ad-campaigns/operations/create-campaign.sh \
  --platform google_ads \
  --campaign-name "Over Budget Test" \
  --daily-budget 600 \
  --lifetime-budget 1000 \
  --target-audience '{}'
# Expected: Exit code 3, error message

# Test lifetime budget violation
./.claude/skills/cfn-marketing-ad-campaigns/operations/set-budget.sh \
  --campaign-id test_campaign \
  --lifetime-budget 6000
# Expected: Exit code 3, error message
```

## Security Considerations

1. **API Key Protection**: Never log N8N_API_KEY
2. **Input Validation**: All parameters sanitized before API calls
3. **Budget Limits**: Hard-coded maximum limits prevent overspending
4. **Rate Limiting**: Respect platform API rate limits
5. **Audit Logging**: All budget changes logged to stderr

---

## Maintenance

**Dependencies:**
- bash 4.0+
- jq 1.6+
- curl 7.0+
- bc (for budget calculations)

**Update Frequency:** Monthly platform API compatibility checks
