  title: Twilio Verify Provision a Service and Run a Verification
  summary: Create a Verify service, start a verification on it, and check the supplied code.
  description: >-
    An end-to-end onboarding flow for Twilio Verify. The workflow first creates
    a new Verify service with a friendly name and code length, then starts a
    verification on that freshly created service, and finally checks the
    user-supplied code against the verification. This chains service
    provisioning into the two-factor flow so a brand new tenant can be stood up
    and exercised in one pass. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
