  title: Tango Onboard Customer and Account
  summary: Create a customer, provision a funding account under it, and confirm the account balance.
  description: >-
    The standard Tango RaaS onboarding pattern. The workflow creates a new
    customer in the platform, provisions a sub-account under that customer to
    hold a reward funding balance, and then reads the account back to confirm it
    was created and to capture its starting balance. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description. Authentication uses the platform's HTTP Basic
    credentials declared by the basicAuth security scheme; those credentials are
    applied at the transport layer and are not request parameters.
