Welcome to xPress!


The Access 4 Learning (A4L) Community, formerly the SIF Association, has concentrated almost 20 years of practical experience solving these problems into its latest solution - xPress!

xPress is a new line of open, standard APIs that provide schools and developers with a way to simply and securely exchange data among modern apps, whether they are hosted locally, in the cloud, or on mobile devices. xPress APIs are developed from real-world use cases, with an explicit focus on practical, easy to implement solutions that use contemporary technologies. The xPress API suite embodies simplicity in its design by using contemporary technologies like REST and OAuth, enabling direct communication among systems (the “broker” is optional) and representing commonly used data in a straightforward manner.
