The generated JSON is then parsed, validated, converted to a downloadable file, and returned to the caller as a binary response.\n\n**Data flow:**\n1. **Receive Workflow Prompt** \u2014 Accepts POST request with a `prompt` field describing the desired automation.\n2. **Sanitize & Normalize Prompt** \u2014 Cleans whitespace and line breaks to ensure consistent input.\n3. **Generate Workflow via AI Agent** \u2014 Sends the prompt to Azure OpenAI GPT-4o-mini with strict system instructions to return only raw JSON.\n4. **Parse & Validate AI JSON Output** \u2014 Parses the AI's string output into a structured JSON object, throwing errors on invalid responses.\n5. **Convert Workflow to JSON File** \u2014 Wraps the parsed JSON into a downloadable `.json` binary file.\n6. **Return JSON File to Caller** \u2014 Sends the binary file back as the webhook HTTP response.\n\n### Setup steps\n1. Configure your **Azure OpenAI credentials** (`azureOpenAiApi`) in n8n credentials.\n2. Ensure your Azure deployment uses the `gpt-4o-mini` model name.\n3. Activate the workflow and copy the webhook URL.\n4. Send a POST request with body: `{ \"prompt\": \"Your automation description here\" }`\n\n### Customization\n- Swap `gpt-4o-mini` with another Azure deployment for higher quality output.\n- Extend the AI system prompt to enforce additional n8n node types or coding standards."
