# Authorization

The Ping Proxies Private User API is reserved for pre-approved applications and therefore, requires both application and user inputted authorization.

{% endcontent-ref %}

{% content-ref url="/pages/ZjKAnC1tENLCMVz15HTH" %}
[User Authorization](/basic-concepts/authorization/user-authorization.md)
{% endcontent-ref %}

{% hint style="info" %}
The API is intended to be used by applications which pass-through user-inputted data and actions.

It therefore also requires additional information such as user IP address and User-Agent to be sent in headers to ensure that rate-limiting and bruteforce blocks work correctly.
