Connect with FreestyleLibre

With Terra's FreeStyle Libre integration, you can allow your users to share their blood glucose information with your app. By scanning their FreeStyle Libre Sensors (compatible with FreeStyle Libre 1, FreeStyle Libre 2, and FreeStyle Libre 3 systems) in their LibreLink app, users will share their Blood Glucose data with your app through the Terra API Integration. This will push raw glucose values, glucose trends, and glucose alarms to your app so you can closely track your users' glucose levels through an easy-to-use API

Recent Data with Webhooks

Historical Data with HTTP Requests

When data is available from an Apple device, it will be streamed to you via our webhooks. During your Terra account setup, you'll be prompted to provide a callback URL, allowing Terra to PUSH data using POST requests.

You may also use HTTP requests with your Apple integration in case you wish to request historical data or data over extended periods of time.

Our Apple integration with Terra offers instant data delivery, eliminating the need for periodic requests. Apple notifies Terra whenever new data is available, and we then POST the normalized data to your webhook.

Most HTTP endpoints can take additional parameters start_date and end_date which allow you to request data over a specific period for the given user.

Terra API preserves the raw data from the wearable, it just standardizes the units and the json format. It doesn’t augment or change the raw data in any way.

Data is organized into one of 6 data types.

People Often Ask Us...

Can I scan the CGM directly in my app?

CGM scanning from within your app is not possible due to legal regulations around medical devices, and restrictions imposed by Abbott. You may however continue to use the official Libre apps, and retrieve FreestyleLibre data via the web API.

What FreestyleLibre sensors can I access through Terra?

Any sensor which syncs to the Libreview cloud is compatible with the Terra API. This includes Freestyle Libre 1, 2, 3, and Pro models.

How quickly does the data sync from the device?

Data from FreestyleLibre can be polled as often as every 5 minutes, which means the delay between a scan and you receiving the data is on the order of a couple minutes at most.
