То, как я делал это в прошлом, это использование тега <merchanrt-private-data>
в исходной корзине, что-то вроде:
<checkout-shopping-cart xmlns='http://checkout.google.com/schema/2'>
<shopping-cart>
<merchant-private-data>
<merchant-note>[some secret about the cart on my system]</merchant-note>
</merchant-private-data>
<items>
...
</items>
</shopping-cart>
</checkout-shopping-cart>
Затем, после того как Google перезвонил с серийным номеромЯ использую API истории уведомлений для извлечения деталей заказа, который затем включает мои личные данные, например:
<new-order-notification xmlns="http://checkout.google.com/schema/2" serial-number="[serial number from google]">
<buyer-billing-address>
...
</buyer-billing-address>
<timestamp>...</timestamp>
<google-order-number>...</google-order-number>
<order-summary>
<total-chargeback-amount currency="GBP">...</total-chargeback-amount>
<google-order-number>...</google-order-number>
<total-charge-amount currency="GBP">...</total-charge-amount>
<total-refund-amount currency="GBP">...</total-refund-amount>
<purchase-date>...</purchase-date>
<archived>false</archived>
<shopping-cart>
<merchant-private-data>
<merchant-note>[the secret about the cart from my system]</merchant-note>
</merchant-private-data>
<items>
</items>
</shopping-cart>
<order-adjustment>
...
</order-adjustment>
<promotions />
<buyer-id>...</buyer-id>
<buyer-marketing-preferences>
<email-allowed>false</email-allowed>
</buyer-marketing-preferences>
<buyer-shipping-address>
...
</buyer-shipping-address>
<order-total currency="GBP">...</order-total>
<fulfillment-order-state>NEW</fulfillment-order-state>
<financial-order-state>REVIEWING</financial-order-state>
</order-summary>
<shopping-cart>
<merchant-private-data>
<merchant-note>[the secret about the cart from my system]</merchant-note>
</merchant-private-data>
<items>
</items>
</shopping-cart>
<order-adjustment>
...
</order-adjustment>
<promotions />
<buyer-id>...</buyer-id>
<buyer-marketing-preferences>
<email-allowed>false</email-allowed>
</buyer-marketing-preferences>
<buyer-shipping-address>
...
</buyer-shipping-address>
<order-total currency="GBP">...</order-total>
<fulfillment-order-state>NEW</fulfillment-order-state>
<financial-order-state>REVIEWING</financial-order-state>
</new-order-notification>
. Затем я могу использовать секрет, чтобы сопоставить заказы додетали, которые я ранее сохранил в базе данных.
