BuyerIdentity must be provided either by createCart mutation or by updateCartBuyerIdentity mutation before checkout. Otherwise, BUYER_IDENTITY_MISSING error will be returned upon cart submission.
For SHOPIFY orders, Rye sends receipts for the placed order to the email set in the buyer identity. For AMAZON orders however, Rye does not send receipts. If you are applying a margin to the product, consider sending a customized receipt, taking information from our ORDER_PLACED webhook.
