Start receiving data from My Macros+ on your app or website



When data is available from a My Macros+ device, Terra sends it straight to your webhook. During your Terra account setup you'll be prompted for a callback URL, and that is where Terra POSTs each payload.

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.

Data can also be sent as a FIT File or with the FHIR Format.
