Send a PDF by fax

send_fax

Send a PDF to a fax number and track delivery, priced per transmitted page. Give a destination in E.164 form (for example +15025551212; US, Canadian and Mexican numbers only) and the PDF: an artifact_id from any earlier result, a job_id from fill_form_from_context or commit_proposal once get_job reports ready, a form_id for the fillable form, or one PDF by pdf_url or pdf_base64, or a sources list of artifact ids (each with an optional pages range such as 1-3,7) faxed together as one packet. Returns a job id at once; poll get_fax for delivery. Billed per page at delivery; a failed fax is not charged.
