Custom Headers come in handy when you need to add your own headers (user agents, cookies, referrer, etc.) to the request.

You can enable Custom Headers by adding &custom_headers=true to the request. The Python and Node SDKs will set this parameter automatically if headers are sent.

Device

If you require to use either desktop or mobile user agents in the headers, you can use &device=desktop or &device=mobile parameter in the request.
