file_type can be any of the following:
- 'pdf' for regular PDF-based contracts,
- 'presigned_pdf' for PDF-based contracts that are already signed
- 'private_template' for contracts based on Officient templates available in your account
Tip:
- template_id is only required when file_type = private_template
- pdf_base64 is only required when file_type is either pdf or presigned_pdf
Scope required: contracts.write
