Get an API key
Create a key from Settings → API Keys with at least the render:write scope. The raw key is shown once, at creation — copy it somewhere safe.
A key is bound to exactly one workspace and can never act on another, even if you pass a different workspace id in the request.

Design a template
Open the studio and build your design. Give any text, image or color-fill layer a variableName — that name becomes a key you can override at render time without touching the saved design. Copy the template's id from its URL or the templates list.
