# Why is my Garmin webhook delivery delayed by about an hour?

Terra delivers Garmin data within seconds of receiving Garmin's push. The delay sits upstream: **Garmin only pushes once the device syncs with the Connect app**, which can take 30 to 90 minutes. There is no on-demand pull for Garmin, so this lag is expected.

Separately, if your auth counts spike, check that your [webhook handler](https://docs.tryterra.co/health-and-fitness-api/user-authentication/handling-authentication-events) does not start a new auth flow on `user_reauth` or `deauth` webhooks:

* `user_reauth` simply signals that the user got a new connection. Update `old_user` to `new_user`.
* It is not an instruction to re-authenticate.
