Two ways to receive Core data
When data is available from a Core 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.
Core does not notify Terra when data changes, so Terra polls it every 5–10 minutes for each connected user and POSTs the normalized payload to your webhook.
Core's Body
Payload Preview
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.
