The filled PDF is flattened (non-editable) and saved to Google Drive.\n\n**The sample form has these fields:**\n- FullName (text)\n- ID (text)\n- Gender (radio: Male / Female)\n- Married (checkbox: true / false)\n- City (dropdown: e.g. New York, Berlin, ...)\n- Language (optionlist: e.g. English, German, ...)\n- Notes (text)\n\n**Use Case:** A company that regularly fills the same government or compliance PDF forms -- permit applications, registrations, insurance declarations. The AI reads whatever fields the form has and maps the right values automatically.\n\nClick \"Test Workflow\" to run it once with the sample form.\n\n### How it works\n1. **Download PDF Form** -- Fetches the fillable PDF from a URL.\n2. **Upload PDF Form** -- Uploads it to Autype Tools.\n3. **Get Form Fields** -- Autype extracts field names, types, options, read-only flags as metadata.\n4. **AI Agent** -- Receives the field list and applicant data as a prompt. The system message instructs the AI to return raw JSON only.\n5. **Prepare Fill Data** -- Parses and validates the AI JSON output, pairs it with the file ID.\n6. **Fill PDF Form** -- Autype fills all fields and flattens them (non-editable).\n7. **Save Filled PDF to Drive** -- Uploads the completed PDF to Google Drive.\n\n### Requirements\n* **Autype account** -- [app.autype.com](https://app.autype.com) > Settings > API Keys\n* **OpenAI account** -- API key from [platform.openai.com](https://platform.openai.com)\n* **Google Drive** -- OAuth2 credential in n8n (optional)\n* **n8n-nodes-autype** -- Install via Settings > Community Nodes\n\n> Community node: requires self-hosted n8n.
