Update buyer identity

Cart buyer identity is used for associating customer information with a cart. You should update cart buyer identity when customer information is available:

Update countryCode when a customer changes site currency or locale so the cart will return pricing in the correct currency.
Update customerAccessToken when a customer logs into a customer account so the cart will return selected delivery options.

This guide shows you how to use the cart handler to update buyer identity.
