Liferay DXP's use of JSONWS API allows the modification of roles in the following manner:
- setting a user's roles - /role/add-user-roles
- unsetting a user's roles - /role/unset-user-roles
- set/unset a user's group roles - /usergrouprole/update-user-group-roles
When it comes to Organization roles, it seems like there is no way to change it through the service, even if it's possible in the UI.
Permit the ability to set/unset a user's organization roles through jsonws api.
