} Generate this document via the API
One template plus changing data is the whole point. The list of blanks above is the contract, and every new set of values comes back in the same layout: fill it in the app, hand someone a form link, or POST the JSON and get the file straight back.
The request below carries this page's own values, so it runs as soon as the template exists in your workspace. Swap the values for yours and the response is your document.
