📱🤖 Create Stunning AI Images Directly from WhatsApp with Gemini

This workflow transforms your WhatsApp into a personal AI image generation studio. Simply send a text message with your idea, and this bot will use the advanced prompt engineering capabilities of Gemini 2.5 Pro to craft a detailed, artistic prompt. It then uses Gemini 2.0 Flash to generate a high-quality image from that prompt and sends it right back to your chat.

It's a powerful yet simple way to bring your creative ideas to life, all from the convenience of your favorite messaging app!

What this workflow does

  • Listens for WhatsApp Messages: The workflow starts automatically when you send a message to your connected WhatsApp number.
  • Enhances Your Idea with AI: It takes your basic text (e.g., "a knight on a horse") and uses Gemini 2.5 Pro to expand it into a rich, detailed prompt perfect for image generation (e.g., "A cinematic, full-body shot of a stoic knight in gleaming, ornate silver armor, riding a powerful black warhorse through a misty, ancient forest. The scene is lit by ethereal morning sunbeams piercing the canopy, creating dramatic volumetric lighting and long shadows. Photorealistic, 8K, ultra-detailed, award-winning fantasy concept art.").
  • Generates a Unique Image: It sends this enhanced prompt to the Google Gemini 2.0 Flash image generation API.
  • Prepares the Image: The API returns the image in Base64 format, and the workflow instantly converts it into a binary file.
  • Sends it Back to You: The final, high-quality image is sent directly back to you in the same WhatsApp chat.

Nodes Used

  • 🟢 WhatsApp Trigger: The entry point that listens for incoming messages.
  • 🧠 LangChain Chain (LLM): Uses Gemini 2.5 Pro for advanced prompt engineering.
  • ➡️ HTTP Request: Calls the Google Gemini 2.0 Flash API to generate the image.
  • 🔄 Convert to File: Converts the Base64 image data into a sendable file format.
  • 💬 WhatsApp: Sends the final image back to the user.

Prerequisites

To use this workflow, you will need:

  • An n8n instance.
  • A WhatsApp Business Account connected to n8n. You can find instructions on how to set this up in the n8n docs.
  • A Google Gemini API Key. You can get one for free from Google AI Studio.

  2. Configure the Gemini 2.5 Pro Node:
    • In the n8n workflow, select the Gemini 2.5 Pro node.
    • Under 'Connect your account', click 'Create New' to add a new credential.
    • Paste your Gemini API key from the previous step and save.
  3. Configure the Generate Image (HTTP Request) Node:
    • Select the Generate Image node.
    • In the properties panel on the right, find the Query Parameters section.
    • In the 'Value' field for the key parameter, replace "Your API Key" with your actual Google Gemini API Key.
  4. Connect WhatsApp:
    • Select the WhatsApp Trigger node.
    • Follow the instructions to connect your WhatsApp Business Account credential. If you haven't created one, the node will guide you through the process.
  5. Activate and Test:

    • Send a message to your connected WhatsApp number (e.g., "A futuristic city in the style of Van Gogh"). The bot will process your request and send a stunning AI-generated image right back to you!

Create Stunning AI Images Directly from WhatsApp with Gemini

This n8n workflow empowers you to generate AI-powered images directly from your WhatsApp conversations using Google Gemini. Simply send a text prompt to your WhatsApp Business account, and the workflow will process it, generate an image, and send it back to you.

What it does

This workflow automates the following steps:

  1. Listens for WhatsApp Messages: It acts as a webhook, waiting for incoming messages to your configured WhatsApp Business Cloud account.
  2. Generates Image Prompt with Gemini: The received WhatsApp message is passed to a Google Gemini Chat Model, which refines or converts the text into an optimal prompt for image generation.
  3. Generates Image via HTTP Request: The refined prompt is then sent to an external image generation API (e.g., DALL-E, Stable Diffusion, Midjourney via an API wrapper) using an HTTP Request node.
  4. Converts Image to File: The generated image data (likely base64 encoded or a URL) is converted into a file format suitable for sending via WhatsApp.
  5. Sends Image Back to WhatsApp: The generated image is sent back to the original sender on WhatsApp.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance (self-hosted or cloud).
  • WhatsApp Business Cloud Account: Configured and connected to n8n with the necessary credentials.
  • Google Gemini API Key: For the "Google Gemini Chat Model" node to process and refine text prompts.
  • Image Generation API Endpoint: An API endpoint for an AI image generation service (e.g., DALL-E, Stable Diffusion, Midjourney API wrapper). This workflow uses a generic "HTTP Request" node, so you'll need to configure it with your chosen service's URL and authentication.

Setup/Usage

  1. Import the Workflow:
    • Download the provided JSON file.
    • In your n8n instance, go to "Workflows" and click "New".
    • Click the "Import from JSON" button and paste the workflow JSON or upload the file.
  2. Configure Credentials:
    • WhatsApp Business Cloud:
      • Click on the "WhatsApp Trigger" node and the "WhatsApp Business Cloud" node.
      • Click on "Credential" and select an existing WhatsApp Business Cloud credential or create a new one. Follow the n8n documentation for setting up WhatsApp Business Cloud credentials.
    • Google Gemini Chat Model:
      • Click on the "Google Gemini Chat Model" node.
      • Click on "Credential" and select an existing Google Gemini credential or create a new one. You will need your Google Gemini API key.
    • HTTP Request (Image Generation API):
      • Click on the "HTTP Request" node.
      • Configure the URL, Method (likely POST), Headers (for API key/authentication), and Body (to send the prompt generated by Gemini) according to your chosen image generation API's documentation.
  3. Activate the Workflow:
    • Once all credentials and configurations are set, click the "Activate" toggle in the top right corner of the n8n workflow editor.

Now, whenever you send a message to your WhatsApp Business Cloud number, the workflow will trigger, generate an image, and send it back to you!

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
