# Security Notes

* Store API keys securely on your backend.
* Never expose API keys in client-side code.
* Use HTTPS for all requests.
* Rotate keys periodically via `/business/api-keys/regenerate`.
* Use your **test key** for sandbox development and your **production key** only for live traffic.
* Do not mix test and production credentials inside the same integration flow.
