This integration strategy is similar to the previous one. It also eliminates the need for POS to interact with the terminal directly; the terminal integration is accomplished using a customizable payment page, which has a built-in integration with a terminal. The approach is particularly convenient for those who already use payment page solution for their online payments or for swiper based retail processing. This integration strategy suits those who do not need very elaborate POS functionality (handling items, discounts, points, etc) and who want to deal with on-line payments and retail payments through the same unified page.
The integration is accomplished using classical payment page approach and the outcome of the transaction (similarly to the Gateway Integration strategy) is posted back to the POS server via callback (notification) URL provided as part of the initial transaction request (issued by POS). This integration strategy has the same two limitations as the Gateway Integration strategy, and is not appropriate for system with no centralized application server. Despite its limitations, this strategy can satisfy 100% of the processing needs of an average POS system. For more information on this strategy, please see the
gateway integration specification and
integration notes as well as

payment page.
