Interfaces
DeviceId
| Prop | Type | Description | Since |
|---|---|---|---|
identifier | string | The identifier of the device as available to the app. This identifier may change on modern mobile platforms that only allow per-app install ids. On iOS, the identifier is a UUID that uniquely identifies a device to the appโs vendor (read more). on Android 8+, the identifier is a 64-bit number (expressed as a hexadecimal string), unique to each combination of app-signing key, user, and device (read more). On web, a random identifier is generated and stored on localStorage for subsequent calls. If localStorage is not available a new random identifier will be generated on every call. | 1.0.0 |
