Google have recently emailed all Google Apps administrators to notify them of the discontinuation of the old provisioning API services. This is the service that manages the provisioning of users from your MIS to realsmart and then to Google Apps
We wanted to let you know that realsmart are managing the change of APIs for all the schools we work with and will very soon launch a new provisioning service. The new provisioning APIs allow us to provide a faster, more efficient service and we will keep you updated with improvements to the service.
There is no need for domain administrators to change anything as this will be managed by the realsmart development team. We are currently testing the new API and will be ready to migrate to the new version before the deadline set by Google.
