# What source IPs should I allow for Terra webhooks?

Terra's [webhook source IPs](https://docs.tryterra.co/health-and-fitness-api/integration-setup/setting-up-data-destinations/webhooks) are documented and rarely change, so **first compare your allowlist against the current list in the docs.**

If the entries match, the cause is usually proxy/CDN handling:

* Verify which header carries the original client IP (`cf-connecting-ip` vs `x-forwarded-for` vs `x-real-ip`).
* Log the rejected values to see what is actually arriving before the whitelist check.
