# Authentication

The ComplyCube API uses API keys to authenticate all requests. You can view, manage, and rotate your keys from the [API keys page](https://portal.complycube.com/developers). 

Sandbox environment keys have the prefix `test_` whereas Live environment keys have the prefix `live_`.

{% hint style="info" %}
All API requests must be made over HTTPS. Any requests made over HTTP will fail.
{% endhint %}

{% hint style="warning" %}
Your API keys carry many privileges, so be sure to keep them secure. Do not share your API keys in publicly accessible areas such as GitHub, client-side code, and so forth.
{% endhint %}
