# Create Folder

> Create a folder at the root of the library or inside parent_folder_id. Team folders need an editor or admin behind the API key. When a folder already exists at the same path the response is 409 with code folder_already_exists and details.existing_folder_id, so a retry can use that folder.

> [!NOTE]
>
> Minimum required API key scope: `Read/Write`

# Use Cases

* **Set Up a Project**: Create a folder tree for a new project or client.
* **Safe Retries**: When the folder already exists, the `409` response includes `existing_folder_id`, so a script or agent can use that folder and continue.

        Create a folder at the root of the library or inside parent_folder_id.
        Team folders need an editor or admin behind the API key. When a folder
        already exists at the same path the response is 409 with code
        folder_already_exists and details.existing_folder_id, so a retry can use
        that folder.
