  title: Amazon Pinpoint Send and Verify OTP
  summary: Send a one-time passcode to a recipient then verify the code they supply.
  description: >-
    Implements the two-leg one-time passcode flow: first an OTP is generated and
    delivered to a destination identity over SMS, then the code the recipient
    enters is verified against the same reference id. The verify step branches on
    whether the OTP was valid. Each step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
