# Custom Proxy Server

> Qonversion SDKs support Proxy URL settings. For example, you can use this feature for the following tasks

1. Log SDK requests on your server
2. Proxy SDK requests in case there are some network restrictions

To leverage this feature, set your Proxy URL using the `setProxyURL` function. Once you implement it, all requests from our mobile SDK will be sent to your API, which should proxy that requests to our API and back.
