The buyer gateway specific field is an element in which you may specify to the buyer (as opposed to the Payer). If this element is not sent, the payer’s information will be used instead. If the element is sent with partial information, any missing fields will be sent as empty. In addition to these fields, PayU receives the buyer-specific phone number present in the shipping_address element if provided.
