+        The Public Template API allows users to create templates that serve as blueprints for generating documents with predefined structures. When a template is successfully created, the API returns a unique **template_id** and a **public_url**. The **public_url** is publicly accessible and may be shared with any user, enabling them to generate and sign documents based on the template. However, the template itself cannot be modified through this URL; it can only be used for document creation and signing.
 
         Tip: Upload your PDF document to our [**Debug UI**](https://app.opensignlabs.com/debugpdf), where you can easily add widgets, then copy coordinates, page numbers, and more in a ready-to-use JSON format. Plus, you can directly copy the document's base64 string, making it quick to send to the API.
