Users only need to enter their address once in the special interface in Yandex.Market, and give it to desired stores on request. By inserting the Адрес из профиля в Яндексе button, an online store simplifies the purchase process and increases conversion, since the user is not required to take additional steps when making an order.
The Quick Order API is free for online stores and their users.
