};

return { json: logEntry };

6. Email Delivery

HTML Email Template Pattern:

// n8n Code Node - Generate HTML Email
const campaignData = $json;

const htmlEmail = `
<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <style>
    body { font-family: Arial, sans-serif; line-height: 1.6; color: #333; }
    .header { background: linear-gradient(135deg, #667eea 0%, #764ba2 100%); 
              color: white; padding: 30px; text-align: center; }

`;

return {
  json: {
    html: htmlEmail,
    subject: `🎉 ${campaignData.festival_name} Campaign Ready - Score: ${campaignData.qa_score}/100`,
    to: campaignData.client_email
  }
};

Common Workflow Patterns

Pattern 1: Campaign Trigger via Webhook

// n8n Webhook Node - POST /generate-campaign
{
  "festival_name": "Diwali",
  "product_name": "Premium Smartphones",
  "brand_name": "TechBrand",
  "brand_colors": "blue and white",
  "target_audience": "young professionals",
  "budget_range": "mid-premium",
  "client_email": "client@example.com",
  "user_email": "agent@agency.com"
}

Pattern 2: Campaign ID Generation

// n8n Code Node - Generate Unique Campaign ID
const timestamp = Date.now();
const festivalCode = $json.festival_name.substring(0, 3).toUpperCase();
const productCode = $json.product_name.substring(0, 3).toUpperCase();

const campaignId = `${festivalCode}_${productCode}_${timestamp}`;

return {
  json: {
    ...$json,
    campaign_id: campaignId,
    created_at: new Date().toISOString()
  }
};

Pattern 3: Gemini API Call Configuration

// n8n HTTP Request Node - Gemini API
// Method: POST
// URL: https://generativelanguage.googleapis.com/v1beta/models/gemini-pro:generateContent

const requestBody = {
  contents: [{
    parts: [{
      text: $json.prompt
    }]
  }],
  generationConfig: {
    temperature: 0.7,
    topK: 40,
    topP: 0.95,
    maxOutputTokens: 8192,
  },
  safetySettings: [
    {
      category: "HARM_CATEGORY_HARASSMENT",
      threshold: "BLOCK_MEDIUM_AND_ABOVE"
    }
  ]
};

return {
  json: requestBody
};

Pattern 4: Error Handling and Retry Logic

// n8n Code Node - Error Handler
try {
  const response = $json;
  
  if (!response.candidates || response.candidates.length === 0) {
    throw new Error('No content generated from Gemini API');
  }
  
  const generatedText = response.candidates[0].content.parts[0].text;
  const parsedContent = JSON.parse(generatedText);
  
  return {
    json: {
      success: true,
      content: parsedContent,
      campaign_id: $json.campaign_id
    }
  };
  
} catch (error) {
  return {
    json: {
      success: false,
      error: error.message,
      campaign_id: $json.campaign_id,
      retry_needed: true
    }
  };
}

Pattern 5: Conditional Campaign Deployment

// n8n Switch Node Logic
// Route based on QA score

const qaScore = $json.qa_score;

if (qaScore >= 85) {
  return {
    json: {
      ...$json,
      deployment_path: 'auto_deploy',
      send_email: true,
      approval_needed: false
    }
  };
} else if (qaScore >= 70) {
  return {
    json: {
      ...$json,
      deployment_path: 'human_review',
      send_email: true,
      approval_needed: true
    }
  };
} else {
  return {
    json: {
      ...$json,
      deployment_path: 'revise',
      send_email: false,
      approval_needed: true,
      revision_priority: 'high'
    }
  };
}

Configuration Best Practices

Google Drive Folder Structure

Create this folder structure in your Google Drive:

Festival Campaigns/
├── 2024/
│   ├── Diwali/
│   │   ├── CAMP_12345/
│   │   │   ├── visuals/
│   │   │   ├── copy/
│   │   │   └── reports/

Google Sheets Campaign Log Schema

// Recommended Sheets columns
const sheetColumns = [
  'campaign_id',
  'timestamp',
  'festival_name',
  'product_name',
  'brand_name',
  'target_audience',
  'qa_score',
  'deployment_status',
  'drive_folder_url',
  'email_sent_to',
  'channels_covered',
  'estimated_reach',
  'created_by',
  'approved_by',
  'launch_date'
];

Gemini Model Selection

// Choose model based on task complexity
const modelMapping = {
  festival_research: 'gemini-pro',
  copy_generation: 'gemini-pro',
  visual_prompts: 'gemini-pro',
  qa_review: 'gemini-pro',
  image_generation: 'gemini-pro-vision' // if using vision capabilities
};

Troubleshooting

Issue: Gemini API Rate Limits

// n8n Code Node - Rate Limit Handler
const delay = (ms) => new Promise(resolve => setTimeout(resolve, ms));

async function callGeminiWithRetry(prompt, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    try {
      // API call here
      return response;
    } catch (error) {
      if (error.status === 429) {
        await delay(2000 * (i + 1)); // Exponential backoff
        continue;
      }
      throw error;
    }
  }
}

Issue: Google Drive Upload Failures

// Check binary data format
if (!$binary.data) {
  throw new Error('No binary data found for upload');
}

// Verify file size
const maxSize = 10 * 1024 * 1024; // 10MB
if ($binary.data.fileSize > maxSize) {
  throw new Error('File size exceeds limit');
}

Issue: Malformed JSON from Gemini

// n8n Code Node - JSON Parser with Fallback
function parseGeminiResponse(text) {
  try {
    return JSON.parse(text);
  } catch (e) {
    // Try to extract JSON from markdown code blocks
    const jsonMatch = text.match(/```json\n([\s\S]*?)\n```/);
    if (jsonMatch) {
      return JSON.parse(jsonMatch[1]);
    }
    
    // Try to find JSON object in text
    const objMatch = text.match(/\{[\s\S]*\}/);
    if (objMatch) {
      return JSON.parse(objMatch[0]);
    }
    
    throw new Error('Could not parse JSON from Gemini response');
  }
}

Issue: Email Delivery Failures

// Gmail API error handling
if ($json.error) {
  console.error('Gmail API Error:', $json.error);
  
  // Log to Sheets for follow-up
  return {
    json: {
      campaign_id: $json.campaign_id,
      email_status: 'FAILED',
      error_message: $json.error.message,
      retry_at: new Date(Date.now() + 3600000).toISOString()
    }
  };
}

Issue: Incomplete Campaign Data

// n8n Code Node - Data Validation
function validateCampaignData(data) {
  const required = ['festival_name', 'product_name', 'brand_name', 'client_email'];
  const missing = required.filter(field => !data[field]);
  
  if (missing.length > 0) {
    throw new Error(`Missing required fields: ${missing.join(', ')}`);
  }
  
  // Validate email format
  const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
  if (!emailRegex.test(data.client_email)) {
    throw new Error('Invalid client email format');
  }
  
  return true;
}

Advanced Features

Memory Integration (Future Enhancement)

// Pattern for adding campaign memory
const campaignMemory = {
  brand_guidelines: $('Get Brand Guidelines').all(),
  past_campaigns: $('Query Past Campaigns').all(),
  performance_data: $('Get Performance Metrics').all()
};

const enhancedPrompt = `
${basePrompt}

Historical Context:
- Brand Guidelines: ${JSON.stringify(campaignMemory.brand_guidelines)}
- Top Performing Campaigns: ${JSON.stringify(campaignMemory.past_campaigns.slice(0, 3))}

Generate copy consistent with brand voice and proven patterns.
`;

Multi-Language Support

// Language detection and translation
const supportedLanguages = ['en', 'hi', 'es', 'fr'];
const targetLanguage = $json.target_language || 'en';

if (supportedLanguages.includes(targetLanguage)) {
  const translationPrompt = `
  Translate the following campaign copy to ${targetLanguage}:
  ${JSON.stringify($json.campaign_copy)}
  
  Maintain cultural relevance and marketing impact.
  `;
}

Analytics Integration

// Track campaign performance
const analyticsPayload = {
  campaign_id: $json.campaign_id,
  event: 'campaign_created',
  properties: {
    festival: $json.festival_name,
    channels: $json.channels_covered,
    qa_score: $json.qa_score,
    timestamp: new Date().toISOString()
  }
};

// Send to analytics platform
return { json: analyticsPayload };
