# Can I see the COROS historical-consent choice?

The COROS historical-data consent prompt is shown during their OAuth flow, but **COROS does not return the user's choice in the token response**, so Terra cannot surface it via scopes.

As a workaround, after connection **make a small test** [**backfill request**](https://docs.tryterra.co/health-and-fitness-api/managing-user-health-data/requesting-historical-data) **for a date before the auth date**. If it returns empty data, the user likely declined historical access, and you can flag them on your side accordingly.
