Turn chat prompts in Telegram into on brand AI images in seconds. Great for marketing teams and community managers who want fast visual replies and interactive campaigns without manual design work.

When a user sends a message in Telegram, the Telegram Trigger picks it up. The text becomes the prompt for the OpenAI image tool. The Merge and Aggregate nodes organize the data and keep the image file attached. The Telegram node then sends the new image back to the same user with sendPhoto. Real time chat, instant image creation, and binary file handling work together to boost engagement and reduce wait time.

You will need a Telegram bot token and an OpenAI API key. Map the Telegram message text to the OpenAI prompt and use the image resource. Make sure binary data is enabled and the chatId points to the sender. Expect faster replies, more interaction in chat, and quicker content tests. Useful for contests, quick mockups, product teasers, and visual support hints.

• Telegram Trigger listens for new messages and starts the flow
• OpenAI node turns the message text into an AI generated image
• Merge node combines data from Telegram and OpenAI for clean routing
• Aggregate node keeps all item fields and includes the image binary
• Telegram node sends the image back using sendPhoto to the right chat
• Expression mapping ensures the chatId matches the original sender

• Reduce manual image creation from 20 minutes to under 1 minute
• Cut response time from hours to seconds in Telegram chat
• Automate up to 80% of visual reply requests from users
• Handle up to 10 times more prompt volume without new staff
• Connect Telegram and OpenAI in one flow for faster delivery

1. Import the template into n8n: Create a new workflow in n8n, click the three dots menu, select 'Import from File', then choose the downloaded JSON file
2. You'll need accounts with Telegram and OpenAI. See the Tools Required section above for links to create accounts with these services.
3. In your OpenAI account, create an API key. In the n8n credentials manager, add a new OpenAI API Key credential and paste the key. Save it with a clear name like OpenAI Prod.
4. In Telegram, use BotFather to create a bot and copy the bot token. In the n8n credentials manager, create a Telegram Bot credential and paste the token. Save it with a clear name like Telegram Bot Prod.
5. Open the Telegram Trigger node and select your Telegram credential. Click Test or Listen for Test Event so n8n registers the webhook. Make sure updates include message events.
6. Open the OpenAI node. Select your OpenAI credential. Set the resource to image and set the prompt to the Telegram message text, for example {{ $json.message.text }}.
7. Check the Merge node. Keep it set to merge main inputs so both the trigger data and the AI output continue through the flow.
8. Open the Aggregate node. Choose aggregate all item data and enable include binaries so the generated image file is passed forward.
9. Open the Telegram node. Select your Telegram credential. Set operation to sendPhoto. Turn on binary data and point to the image binary from the OpenAI node. Set chatId to the sender id, for example {{ $json.message.from.id }}. If you merged items, confirm the path matches the aggregate output.
10. Save the workflow and run a test. Send a Telegram message to your bot and confirm an image is returned. If nothing arrives, check the execution logs in n8n for errors.
11. Troubleshoot common issues: invalid bot token, bot not added to the chat, missing include binaries, or an empty prompt. Fix and retest until an image returns reliably.
