Banks and Credit Unions have taken a segmented approach to integrating with third-party apps. Banks vary in their tech resources and infrastructure and apps must choose which banks they are willing to integrate with. Plaid aims to enable every bank and credit union to integrate with a single API.
The LemonStand API provides the ability to integrate its ecommerce tools into almost any website, and is aimed at the midsize merchant market. Built with Php, MySQL and Ajax, it is completely customizable using HTML and CSS. Updates are achieved through a single click. Lemonstand promises an upcoming App store for third party wares.
