User sends a product photo to your Telegram bot\n2. The workflow authenticates with Google Cloud using a Service Account stored in Google Sheets\n3. The image is sent to Vertex AI (Veo 3) with a 360\u00b0 orbit camera prompt\n4. The workflow polls every 2 minutes until the video is ready (up to 10 min)\n5. The finished video is sent back to the user in Telegram\n\n## Setup steps\n1. Create a Telegram bot via @BotFather and add the credentials in n8n\n2. Enable the **Vertex AI API** in your Google Cloud project and request Veo 3 preview access\n3. Create a Service Account with `roles/aiplatform.user` and download the JSON key\n4. Paste the key fields into your Google Sheet \u2014 columns needed: `client_email`, `private_key`, `project_id`, `scope`\n5. Update the **1. Get Service Account Details** node with your Sheet ID\n6. Connect your Google and Telegram credentials, then activate the workflow"
