# How do I fix a Whoop 'authorization expired' error?

An 'Authorization expired, please reauthorize with the data provider' error means the **provider-side token is no longer valid**, usually because the end user revoked your app's access from the provider's portal/app, changed their password, or the provider invalidated or expired the token. Some providers, such as Oura, do not emit a deauth event when this happens.

To fix it, **have the user reconnect through your normal Terra connect flow / widget**. There is no need to deauthenticate first.

* Make sure they accept all requested permissions and complete the entire flow without interruption. Data flow then resumes automatically and missing data can be re-pulled. (Providers like Huawei have a rolling lookback window, so reconnecting sooner recovers more history.)
* For WHOOP specifically, also check the per-key user limit in the [WHOOP developer dashboard](https://docs.tryterra.co/health-and-fitness-api/whoop), as hitting it causes similar failures.
* Ensure your endpoint returns `2xx` to the `connection_error` webhooks Terra sends, since those are the signal a user needs to reauth.
