  title: Paystack Create Charge and Submit OTP
  summary: Create a direct charge, branch when an OTP is required, submit the OTP, then check the final charge status.
  description: >-
    The OTP step of the Charge API's progressive authentication. A direct charge
    is created with the customer's card authorization; when Paystack responds that
    an OTP is required the workflow submits the OTP against the same reference and
    then checks the pending charge for its final status. A branch short-circuits
    to the status check when no OTP is needed. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
