Image Creation with OpenAI and Telegram

This n8n workflow enables users to generate images using OpenAI's DALL-E model directly from Telegram and receive the generated image back in the chat. It simplifies the process of creating visuals by integrating a popular messaging platform with powerful AI capabilities.

What it does

This workflow automates the following steps:

1. Listens for Telegram messages: It acts as a Telegram bot, waiting for incoming messages from users.
2. Generates an image with OpenAI: Upon receiving a message, it uses the message text as a prompt to generate an image via the OpenAI DALL-E model.
3. Sends the image back to Telegram: Once the image is generated, it sends the image URL back to the original Telegram chat.

Prerequisites/Requirements

To use this workflow, you will need:

• n8n Instance: A running n8n instance.
• Telegram Bot Token: A Telegram bot configured with a token. You can create one by talking to BotFather on Telegram.
• OpenAI API Key: An OpenAI API key with access to DALL-E image generation.

Setup/Usage

1. Import the workflow: Download the provided JSON and import it into your n8n instance.
2. Configure Telegram Trigger:
   • Click on the "Telegram Trigger" node.
   • Select or create a new Telegram API credential using your Telegram Bot Token.
   • Set the "Update Type" to "Message".
   • Save and activate the workflow.
3. Configure OpenAI Node:
   • Click on the "OpenAI" node.
   • Select or create a new OpenAI API credential using your OpenAI API Key.
   • Ensure the "Resource" is set to "Image" and "Operation" to "Create".
   • The "Prompt" field should be configured to use the incoming Telegram message text (e.g., {{ $json.message.text }}).
4. Configure Telegram (Send Image) Node:
   • Click on the "Telegram" node.
   • Select the same Telegram API credential used in the trigger node.
   • Set the "Chat ID" to the chat ID from the incoming message (e.g., {{ $json.message.chat.id }}).
   • Set the "Message Type" to "Photo".
   • Set the "Photo" field to the URL of the generated image from the OpenAI node (e.g., {{ $json.data[0].url }}).
5. Activate the workflow: Toggle the workflow to "Active" in n8n.

Now, send a message to your Telegram bot, and it will respond with a generated image based on your prompt!
