The Google beacon platform is deprecated as of December 7, 2020. The platform will shut down on April 1, 2021.


The Proximity Beacon API is a part of the Bluetooth low energy (BLE) beacon platform, which also includes Eddystone, an open beacon format from Google.

The Proximity Beacon API is a cloud service that allows you to manage data associated with your BLE beacons using a REST interface.

You can associate data with your registered beacons as attachments. Attachments are arbitrary blobs of data that are served back as messages to your Android and iOS apps through the Nearby Messages API. You can update attachments remotely, eliminating the need to physically visit each beacon.

You can monitor the health of your beacons through the Proximity Beacon API's diagnostic endpoint, to detect battery levels, determine whether a beacon has been moved, and more.

When you register beacons with the Proximity Beacon API, the following fields are used as a signal by the Places API:

  • Latitude and longitude coordinates.
  • Indoor floor level.
  • Google Places API Place ID.
