The OneSignal integration is available on the Enterprise plan.
Radar can send tags to and trigger notifications in OneSignal. You can create notifications triggered by tag changes. Use the OneSignal integration to send location-triggered and location-targeted messages to increase engagement and conversion.

​
Configuration

On the OneSignal Settings page under Keys & IDs, copy your REST API key. Then, on the Radar Integrations page under OneSignal, set Enabled to Yes and paste your API key. Note that you can set separate API keys for the Test and Live environments. Whenever events are generated, Radar will call the edit device API and set tags in OneSignal. You can create notifications triggered by tag changes. By default, Radar userId and deviceId do not map to OneSignal. To map users in Radar to devices in OneSignal, you must send the OneSignal player ID to Radar by setting metadata.oneSignalPlayerId. For example, on iOS: 
let playerId = OneSignal.getPermissionSubscriptionState().subscriptionStatus.userId
Radar.setMetadata(["oneSignalPlayerId": playerId])
Because OneSignal does not support associating custom events with a user, the most recent event types triggered from a location update are sent as a comma-separated list under the Onesignal tag radar_events. For example, if a user has exited a geofence and entered a place, the value for the radar_events tag would be exited_geofence,entered_place.
