  title: RingCentral Send a Fax and Retrieve the Sent Document
  summary: Send a fax with an attachment, poll the message store until it is delivered, and download the transmitted document.
  description: >-
    Programmatic fax remains a core RingCentral use case in regulated industries
    where a fax transmission is the record of delivery. This workflow posts a fax
    as multipart/form-data with a cover page and an attachment, then polls the
    resulting message store record until the aggregated fax status settles, and
    finally downloads the transmitted document content for archival. Outbound fax
    status aggregates across recipients: RingCentral reports `Queued` while any
    recipient is pending and `SendingFailed` if any recipient fails. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
