Parses raw QR payload content and returns a normalized representation
of the payment data. Optional customer and fiat currency inputs can be
supplied to apply country- or channel-specific parsing rules.

customerId is optional for parsing-only requests. It is required if the
returned qrToken will be used to create a payout order with qrMode set
to TOKEN, because the token is associated with the specified customer.

QR Parse Request Resource.
