Who is this for?

  • Creators, designers, and developers exploring AI-powered image generation.
  • Automation enthusiasts who want to integrate image creation into n8n workflows.
  • Telegram bot builders looking to add visual AI capabilities.
  • Marketers or freelancers automating creative content workflows.

What problem is this workflow solving?

Creating AI images usually requires multiple tools and manual setup. This workflow removes the complexity by:

  • Connecting Nano Banana (AI image model) directly to n8n.
  • Allowing image generation via Telegram chatbot.
  • Providing a no-code setup that is fully automated and scalable.

What this workflow does

This workflow demonstrates how to generate AI images using Nano Banana and n8n, with an integrated Telegram chatbot interface.
The process includes:

  1. Connecting Gemini Nano Banana to n8n.
  2. Automating image generation requests triggered from Telegram.
  3. Returning AI-generated images back to the user.
  4. Allowing customization of prompts and styles dynamically.

By the end, you’ll have a fully functional automation to generate and send AI-created images through Telegram — no coding required.

Setup

  1. Create accounts:
  • Sign up on n8n.io and ensure you have Telegram Bot API access.
  • Connect your Nano Banana or Gemini API endpoint.
  1. Set up your Telegram Bot:
  • Use BotFather to create a new bot and get the token.
  • Add the “Telegram Trigger” node in n8n.
  1. Configure Nano Banana connection:
  • Add an HTTP Request node for Nano Banana API.
  • Insert your API key and prompt parameters.
  1. Handle responses:
  • Parse the AI-generated image output.
  • Send the image file back to the Telegram user.
  1. Test and Deploy:
  • Run a sample image prompt.
  • Verify that Telegram returns the correct generated image.

How to customize this workflow to your needs

  • Modify prompts or styles to fit different artistic use cases.
  • Add conditional logic for image size, aspect ratio, or filters.
  • Integrate with Google Drive or Notion for image storage.
  • Schedule automatic image generation for campaigns or content creation.
  • Expand with OpenAI or Stability AI for hybrid workflows.

Notes

  • Nano Banana API may have rate limits depending on usage.
  • Ensure your Telegram bot has permission to send files and images.
  • You can host this workflow on n8n Cloud or self-hosted setups.
