Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Monitor Geofence Regions on a Mobile Device

A Lightning web component can use a mobile device’s location features to determine a user’s current location to the user’s proximity to areas that may be of interest, or to perform location-related tasks. The longitude, latitude, and radius define a geofence around the regions of interest.

Geofence location is determined locally on the mobile device, and doesn’t need a network connection. However, GeofencingService does require a GPS signal from the device. For Android devices, Google Location Accuracy must be enabled in the system settings. GeofencingService does require access to platform-specific APIs that are available only within compatible Salesforce mobile apps.

GeofencingService does not and cannot function when running in a web browser, whether on a desktop or mobile device.
