# OneSignal
The OneSignal integration is available on the [**Enterprise plan**](https://radar.com/pricing).
Radar can send tags to and trigger notifications in [OneSignal](https://onesignal.com). 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](https://dashboard.radar.com/integrations) 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](https://documentation.onesignal.com/reference/edit-device) 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:
```swift Swift theme={null}
let playerId = OneSignal.getPermissionSubscriptionState().subscriptionStatus.userId
Radar.setMetadata(["oneSignalPlayerId": playerId])
```
```kotlin Kotlin theme={null}
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`.
