# Working With APIs

In some cases, you might want to fetch or post data to a tool that isn't already [Integrated with PixieBrix](https://docs.pixiebrix.com/integrations).&#x20;

To do so, use the `HTTP Request` brick to craft a request to the API of your choice.

The brick exposes a `service` parameter where you can optionally pass a reference to private or shared integration to perform the authentication. If you use a shared integration, the call will be routed through PixieBrix's API proxy, so that the team credentials are not transmitted to the browser.
