While synchronization options with STARFACE are quite diverse thanks to sync.blue® (LDAP, CSV, etc.), we strongly recommend using the sync.blue® app called "STARFACE". This app synchronizes with the private or central STARFACE address book through the STARFACE-side REST API. This API is already enabled by default in STARFACE (HTTP port 80 or HTTPS port 443). There is no need for any special service or module within STARFACE.
