# Custom Domain

## Overview

For Redirect and Direct Response users, the usual domain name encoded onto the tags is the ixkio tag management URL : `https://t.ixkio.com.`&#x20;

However, on all our Flex Direct and Flex Redirect plans, you can also use your own domain and map this to ours.&#x20;

{% hint style="danger" %}
You can only have one domain associated with your account and changing this may cause existing tags to stop working. We very strongly recommend you choose a domain and subdomain that you are good to use in the long term.&#x20;
{% endhint %}

You need to create a CNAME on your domain, for example 'auth.yourdomain.com' or 'tap.yourdomain.com' which maps/points to <https://t.ixkio.com>. You can do this through the company that hosts your company domain.&#x20;

We recommend speaking to your domain holding/hosting company if you need advice on setting this up.&#x20;

Once the CNAME has been set, contact us via email at <mail@ixkio.com> for us to configure this on your Account.&#x20;

Ixkio will create an SSL certificate for you free of charge for your domain on our platform.&#x20;

{% hint style="info" %}
It can take 48-72 hours for a CNAME change to be fully active across the internet.&#x20;
{% endhint %}

## Using a Custom Domain with API

You cannot currently use a Custom Domain for accessing either the Response API or the Management API.&#x20;

In both these cases, your end user would not be aware of the ixkio domain in any event so it's highly unlikely that API Mode users would need or require a Custom Domain. &#x20;
