> [!NOTE]
> Please note that when you use `transparentResponse=true` you will get status codes returned by the target website. If there is a problem caused by the proxy, our system may return 502 status code in addition to the target web page.

> [!WARNING]
> **Authentication Throttling:** Repeated requests with an invalid token may result in temporary IP-level throttling by the authentication server. If your IP is throttled, you will receive the message: `"Your request has been temporarily throttled by the authentication server."` Ensure your token is correct and wait before retrying.
