# Client Area Output Using this function, it is possible to output custom HTML in the Client Area when a client is managing a domain name. Using the `_ClientArea` function, you can return output that will be shown in the Domain Overview when viewing a domain in the Client Area. All the parameters available in other registrar module functions are available to you within this function. Visit the [Module Parameters](https://developers.whmcs.com/domain-registrars/module-parameters/) page for information on the variables available in `$params`. The function should return the HTML to be rendered on the page. Note: We recommend avoiding making remote API calls within this function as doing so will result in increased overheads for page load and potentially slower page load times. ``` /** * Client Area Output. * * This function renders output to the domain details interface within * the client area.
