setGuestEmailOnCart mutation

For guest customers, you must assign an email to the cart before you place the order.

A logged-in customer specifies an email address when they create an account. Therefore, you can place the order without explicitly setting the email.

Syntax

mutation: {setGuestEmailOnCart(input: SetGuestEmailOnCartInput): {SetGuestEmailOnCartOutput}}
