Allows the client to start a cash-in process by generating a CLABE (Clave Bancaria Estandarizada) for deposit. The transaction amount and the payer’s name must be provided in the request. This method does not allow the payer to send a different amount then the requested, and after the payment, clabe is deleted, so it is for a single payment only.
