When a user sends any text or command in Telegram, that message is collected by n8n using the Telegram trigger. Then the text is cleaned and used as a prompt for Nano Banana, which is a small AI image model. The workflow sends this prompt to Nano Banana by using HTTP request node. The model then returns one generated image file. This image is again sent to the same user in Telegram chat automatically.\n\nThe whole process is done inside n8n without any other tools. You can also add a small OpenAI node in between if you want to make better image descriptions. The workflow is built in a simple way so anyone can test, learn, and extend it easily.\n\n### Setup steps\n1. Create your Telegram Bot by using BotFather and copy its token.\n2. Add your Telegram credentials in n8n.\n3. Copy your Nano Banana API key and paste it in HTTP Request node.\n4. (Optional) Add OpenAI credentials for refining prompt.\n5. Turn the workflow on and test by sending a message from your Telegram app."
