Data actions3

Before you assign it

  • It reaches the data, not just the resource. It has 3 data actions, such as reading blobs, secrets or messages.

What it can do

No control-plane actions.

Data actions

PermissionWhat it allows
Microsoft.SignalRService/SignalR/group/readCheck group existence or user existence in group
Microsoft.SignalRService/SignalR/clientConnection/readCheck client connection existence
Microsoft.SignalRService/SignalR/user/readCheck user existence

Assign it

Scope it as tightly as you can: a resource or resource group rather than the whole subscription.
