      intent: Charge a saved payment method
      effect: write
      questions:
      - Can I charge a customer's stored card or bank account through Stax?
      - Is it possible to place a pre-authorization instead of an immediate charge on a saved payment method?
      - Can I tie a charge to an invoice and pass an idempotency key so it is not charged twice?
      instructions:
      - text: 'Charge {total} to payment method {payment_method_id} right now, without a pre-auth: {pre_auth}.'
        slots:
          total: requestBody.total
          payment_method_id: requestBody.payment_method_id
          pre_auth: requestBody.pre_auth
      - text: Pre-authorize {total} on payment method {payment_method_id} with pre_auth set to {pre_auth}.
        slots:
          total: requestBody.total
          payment_method_id: requestBody.payment_method_id
          pre_auth: requestBody.pre_auth
      - text: Charge {total} to payment method {payment_method_id} against invoice {invoice_id} using idempotency key {idempotency_id}, pre_auth {pre_auth}.
