"content": "## Music Producer Chatbot using Gemini + Suno (via Kei AI) with Google Drive Upload\nThis workflow creates an **AI-powered chatbot** that generates **custom songs** through an interactive conversation, then uploads the results to Google Drive. \n\nThis workflow transforms n8n into a complete AI music production pipeline by combining:\n\n* Conversational AI\n* Structured data validation\n* Tool orchestration\n* External music generation API\n* Cloud automation\n\n### **How it works:**\n\nThis workflow orchestrates a full AI music production pipeline inside n8n using a conversational agent, structured validation, asynchronous API handling, and cloud storage. A Google Gemini-powered \u201cMusic Producer Agent\u201d interacts with the user to collect required inputs (title, genre, lyrics source, negative tags), dynamically calling tools for lyric generation or search as needed. The structured output is validated, cleaned, and enforced through strict JSON formatting before being sent to the [Kie.ai API](https://kie.ai?ref=188b79f5cb949c9e875357ac098e1ff5) for music generation via an asynchronous webhook callback. Once the API completes processing, the workflow resumes, retrieves generated tracks, loops through each result, downloads the audio files, and uploads them to Google Drive with properly formatted filenames. The architecture combines LLM agent logic, tool orchestration, and scalable async control flow.\n\n### **Setup steps:**\n\nConfigure three required API credentials: Google Gemini (for chat models), Gemini Search (for lyric lookup), and a [Kie.ai](https://kie.ai?ref=188b79f5cb949c9e875357ac098e1ff5) Bearer Token (for song creation and retrieval). Authenticate Google Drive OAuth2 in the upload node, verify the target folder ID, and ensure write permissions are correctly set. Expose the Wait node webhook publicly and register it as the callback URL in [Kie.ai](https://kie.ai?ref=188b79f5cb949c9e875357ac098e1ff5) settings to enable asynchronous completion handling. Optionally customize agent prompts, music generation parameters (e.g., styleWeight, weirdnessConstraint), vocal settings, or storage paths to fit your use case. After activation, test the workflow via chat input to validate conversational data collection, JSON formatting, API generation, and automated file upload to Drive.\n"
