# Update cPanel account service proxying

`GET /set_service_proxy_backends`

This function lets you configure a cPanel account's
[service proxying](https://go.cpanel.net/ServiceProxying).

**Note:**

* If the cPanel account is a [distributed account](https://go.cpanel.net/cPanelGlossary#distributed-cpanel-account),
and you call this function on the account’s [parent node](https://go.cpanel.net/cPanelGlossary#parent-node),
the system will propagate the new service proxying to the [child node](https://go.cpanel.net/cPanelGlossary#child-node).
* If the [Web Server](https://go.cpanel.net/howtouseserverprofiles#roles) role is active
on the server, this function rebuilds the user's web virtual hosts (vhosts) and restarts
the web server.
* If the system cannot rebuild the user's vhosts, the API call will still succeed. However,
the function returns a failure warning in the metadata.
* To remove an account's service proxying, use the WHM API 1 `unset_all_service_proxy_backends`
function.
