      summary: Create temporary file from a remote URL
      description: 'Downloads a file from the specified remote URL and stores it as a temporary resource. The temporary file can then be referenced when creating content. The URL must pass validation to prevent SSRF attacks. Anonymous access can be allowed via the TEMP_RESOURCE_ALLOW_ANONYMOUS configuration property.


        **Use this endpoint to supply files for binary and image fields** (`ImmutableBinaryField`, `ImmutableImageField`) when a file is already accessible by URL. Send `{"remoteUrl": "https://example.com/image.jpg"}` and pass `tempFiles[0].id` (e.g. `"temp_5311313004"`) as the field value in the workflow fire endpoint. See `PUT /api/v1/workflow/actions/default/fire/{systemAction}` for the full pattern.'
