You can now use the Notion API to create pages directly from your existing templates.

This is a major win for automation, allowing developers to build automated workflows and one-click updates that rely on pre-built templates. The update gives developers the ability to apply a data source template to a newly created page, and it includes a new, optional body parameter called erase_content that helps clear a page’s existing content before reapplying a template.

Developers will need to refer to the official Notion API documentation on creating pages from templates for the specific body parameters and syntax required to call and utilize your existing database and page templates.
