Create a payment order and return checkout URLs / deep links for supported
channels (WEB, H5, APP). The response contains redirect URLs and the list
of available payment methods. Redirect the payer to the returned URL to
complete the transaction.
For PSP merchants only, the optional request field subMerchantCode may be
provided to tag the order with a sub-merchant business code. Non-PSP merchants
sending a non-empty subMerchantCode will be rejected (subMerchantNotAllowed).
Blank / omitted is allowed for all merchants.
