AI Festival Campaign Generator

Skill by ara.so — Marketing Skills collection.

This skill enables AI coding agents to work with the AI Festival Campaign Generator, a multi-agent marketing automation system built with n8n that generates complete festival marketing campaigns including copywriting, visual assets, quality assurance, and automated delivery via email.

What It Does

The AI Festival Campaign Generator orchestrates multiple AI agents to:

• Research festival context and consumer psychology
• Generate multi-channel marketing copy (social media, email, SMS, YouTube)
• Create AI-powered visual assets (product images, banners, stories)
• Perform campaign quality assurance
• Store assets in Google Drive
• Log campaigns in Google Sheets
• Deliver formatted campaign kits via email

Architecture Overview

The system uses a 4-agent architecture:

1. Festival Intelligence Agent: Researches festival, analyzes consumer behavior, recommends offers
2. Campaign Copywriter Agent: Generates copy for 10+ marketing channels
3. AI Visual Generator Agent: Creates and uploads visual assets to Drive
4. Campaign QA Reviewer Agent: Reviews quality and provides deployment score

  url: file.webViewLink,
  id: file.id
}));

return {
  json: {
    campaign_id: $json.campaign_id,
    drive_files: driveFiles
  }
};

};

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; }

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": "[e-mail]",
  "user_email": "[e-mail]"
}

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 };
