AliDropship hosting service comes with a test domain name. It is created automatically once you finish registering an account and looks like u324321044.alisrv.com. The actual name is randomly generated, and you can't choose it. Your test domain name becomes the primary domain name on your hosting account and is unique to you.
It is needed purely for testing reasons and is meant to be replaced with a proper domain name afterwards. You won't be able to create a subdomain for a test domain or use it for your online store since many important functions just won't work. It is also not guaranteed that you will be able to activate free SSL certificate that is included in the hosting service purchase while using a test domain.
If you already have your own domain name, you can address our support team, and we will set it up for you as the primary domain name on your account, or you can set up your domain name as an addon domain name and start building your site. In both cases you will need to point your domain name to your AliDropship server by changing your domain's Name Servers.
You can install WordPress and start building your site on a test domain name. It is possible to change your site's domain afterwards. You will need to purchase a proper domain name and contact our support team. You can choose any domain name registrar to purchase a domain name. Many of our clients use Namecheap or GoDaddy. Please check out this article if you need more information on how to choose and purchase a domain name.
Please note that your theme customization will be set to default settings in the process of changing domains, so we don't recommend to customize your site while using a test domain.
