To streamline the process of defining yuuvis® Momentum role sets, a number of REST endpoints are have been made available to retrieve the current role set structures and to to apply modifications. As seen in the permissions concept page, there are three options used to structure the role set, coming from two endpoint categories. The /system/permissions and /system/apps/{app}/permissions endpoints are both used to modify the global role set applicable to all users of the system, whereas the /admin/permissions endpoint serves to change the role set specific to the current tenant. 

Complete role set files can be supplied to one of the endpoints via an HTTP POST request, overwriting the previous role set present at that positionlocation. Thus, retrieving and extending the previous role set state by using a GET request on the same endpoint is strongly recommended. New role sets can also be validated by posting them to the role set endpoint URLs using the added URL suffix /validate.
