Allows a Buyer to submit offers/terms for an Application to prepare a checkout in a Merchant store.
. This runs BOF for use by the Checkout Experience, without completing application checkout.
A short code will be generated and linked to the created application and selected offer.
Application status will be updated to ATTEMPTED_PREPARE_CHECKOUT, and finally CHECKOUT_PREPARED after actual application checkout.
