The Beacon Registry allows providers to create and maintain a registration record for the UUID/major/minor combination of any Bluetooth Low Energy device, including iBeacons. The API uses HTTP PUSH and accepts/returns data in XML or JSON. Use the API to program specific information that will be pushed to a user when in proximity of your Bluetooth Beacon.
The following is a list of SDKs from our SDK directory that matched your search term. Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API.
