  title: emnify Send SMS to Endpoint
  summary: Authenticate, confirm the endpoint exists, then send a mobile-terminated SMS to it.
  description: >-
    A messaging flow for delivering a mobile-terminated SMS (MT-SMS) to a
    connected device. The workflow authenticates, looks up the endpoint to
    confirm it exists and capture its status, and then sends the SMS payload
    with the supplied sender address. Every step spells out its request inline,
    including the Bearer Authorization header threaded from the authenticate
    step.
