## 3. Send OneSignal Notifications

Once your OneSignal account is connected, you can add steps to perform the following actions:

* Send notification to segment

* Send notification to specific devices (player IDs)

* Send notification to specific devices (external IDs)

* Send notification to users based on filters

When entering notification content or using a template in OneSignal you can reference data from previous steps by typing `{{` to invoke the variable menu.
