How the Coros API integration works
- Data delivery
- Terra polls Coros
- Expected latency
- Up to 5–10 minutes after the provider syncs
- Data types
- Activity, Daily and Sleep, normalized by the Terra unified API
- Credentials
- Terra manages the Coros API credentials, so there is nothing to register
Two ways to receive Coros data
When data is available from a Coros 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.
Coros 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.
Coros's Activity
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.

Activity Payload (JSON)
{
active_durations_data: { ... }
calories_data: { ... }
data_enrichment: { ... }
distance_data: { ... }
heart_rate_data: { ... }

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

The Data Behind the London Marathon
While Sabastian Sawe was busy breaking the two-hour marathon barrier in London, the watches of 571 amateur runners told a quieter but equally fascinating story. GPS devices over-measured the course by 527 metres on average, faster runners ran with higher heart rates than the slower ones did, and Coros watches reported 47% more calories per kilometre than physiology actually supports.
