Replace the form template's fields
Replace the complete ordered list of content blocks, and return the template. Include existing IDs to keep fields; omit an ID to create a field. Fields you leave out are deleted. An existing field’s type can’t change. PDF ownership, metadata and section locks are validated. Read the form again to see the keys a question can bind to. Requires forms:write and documents:write, including for drafts.
