Hello Pietro,

to grant access to APIs and Websocket connections go to your App project and have a look to the file "yourcompany-yourappMANAGER.js".

From line 50 you should see the variable/list "typeCheckmarks". In the first line you define the rights for the Users app and in the second line the rights for the Admin app by simply setting the corresponding value from False to True. The Admin App uses the websocket connection of the Users App, no True on WebSocket should be necessary here.
The rights are set when the app object is created via the PbxManager.

Best regards

Mladen
