# Authentication

To make direct HTTP requests to the Stream API, you must include your Sitecore CDP client key as a query string parameter in the URI of the request.

To find your client key, in Sitecore CDP, on the navigation pane, click ![cdp_gear_icon.png](https://doc.sitecore.com/api/markdown-image/cdp/en/developers/api/images/cdp_gear_icon.png) > **API access** > **Client key**.

Example 29. Sending a client key with a request when retrieving the browser ID

```curl
curl -X GET -g '<baseURL>/v1.2/browser/create.json?client_key=<client_key>'

```
