When a PDF is generated by PDFMonkey, retrieve the PDF file and use it as needed.
### Configuration
Copy the webhook URL and add it to your PDFMonkey Webhooks dashboard ([PDFMonkey Webhooks](https://dashboard.pdfmonkey.io/webhooks)) to define your N8N callback URL in your PDFMonkey account.
For more information, visit: [PDFMonkey Webhooks Documentation](https://docs.pdfmonkey.io/pdfmonkey-features/webhooks#defining-a-workspace-wide-webhook)
### Usage
On success: Download the generated PDF.
On failure: Handle it as needed. 😉
