Hello everybody.
I’m currently seeking a solution to automatically populate buyer information during the checkout process. I’ve been experimenting with a checkout UI extension developed in React. When a buyer navigates to the checkout panel, I invoke an external API using his email to retrieve his shipping and billing address details (as the user information is stored in a separate system). I can successfully update the shipping address using the useApplyShippingAddressChange() hook. However, I’m facing a challenge when it comes to modifying the billing address. Is this not supported? every help is really appreciated, thanks a lot
