# Get the template variables schema

> Returns a JSON Schema describing the variables the template’s published version expects — one labelled string property per variable, with required variables listed. Use it to build dynamic input forms or validate `variables` before creating passes; the Power Automate connector uses it to render the Create Pass fields.

Requires the `templates:read` scope on the access token.
