Purchase/Transfer of Alphaskin Products

We need to implement a scenario that guarantees the delivery of an alphaskin to a user: the ability to purchase alphaskins via the API for a service account, store them on the platform’s balance, and, if necessary, transfer a specific alphaskin to a user via Steam ID or a trade link. It is necessary to define the available workflow and API methods that ensure a 100% success rate for the user in receiving the selected alpha skin at the specified price.
