Purpose & Audience

Perfect for marketing teams, agencies, solopreneurs, and e-commerce brands who need fast, professional-quality ad creatives — without hiring designers or using Canva. This workflow automates image generation for Facebook, Instagram, and Pinterest using Google’s Imagen 3.0 (via Gemini API).

What It Does

  1. Presents a user-friendly form to collect:
    • Business context
    • Offer/message
    • Brand colors
    • Target platform (FB/IG/Pinterest)
    • Desired ad dimensions (7 formats supported)
  2. Uses Google Gemini’s Imagen 3.0 model to generate platform-optimized images
  3. Delivers each image directly to your Telegram chat with clear captions

✅ Supports 7 ad formats:

  • Facebook Feed (1200×630)
  • Facebook Story (1080×1920)
  • Instagram Feed (1080×1080)
  • Instagram Story & Reel (1080×1920)
  • Pinterest Pin (1000×1500)
  • Pinterest Story (1080×1920)

How to Set Up

  1. Get a Google Gemini API key at ai.google.dev (enable Imagen API)
  2. Create a Telegram bot via @BotFather and note your Bot Token + Chat ID
  3. In n8n:
    • Import this workflow
    • Add Google Gemini credentials (use your API key)
    • Add Telegram credentials (use your Bot Token)
    • Replace ={{ $json.telegramChatId }} in Telegram nodes with your actual numeric Chat ID
  4. Activate the workflow and share the Form Trigger URL with your team!

💡 Pro Tip: Enhance prompts in Gemini nodes with style keywords (e.g., “minimalist”, “vibrant”, “corporate”) for better results.

✨ 100% free to use — only pay for Google Imagen API usage. Telegram delivery is free forever.
