Fill a form from values

fill_form

Fill a PDF form from structured data such as JSON or key-value answers. Fill a ready form with values keyed by field id or field label. Checkboxes take yes or no; choice fields need one of their options. flatten is reserved and not available yet. Returns a download link plus any labels that did not match (ask the user about those). Billed as one fill; the first 5 each month are free. retention (ephemeral or account_default) is accepted but changes nothing: the form keeps the setting it was created with.
