Use a Custom Subdomain with Square Online
If you want to start selling online without changing your website or leaving your current web host, using a subdomain might be a good solution. A subdomain is a separate web address created from an existing domain name. So if your website is www.mysite.com, you might set up a subdomain like shop.mysite.com for your online store. There are two parts to setting up a subdomain, the first is getting the IP address for your online store and the second is creating the subdomain in your domain name settings.
Finding the IP Address
To identify your websites IP Address:
Log into the Square Online Overview page.
Go to Website > General Settings
In the Site Address section, click the Customize button.
In the pop-up menu, select Use a domain I own.
Type in the full subdomain you want to use and click Verify.
Select Connect my domain and click Next.
Connect your domain basic setup information and the IP address will appear in the POINTS TO column.
Copy and save the IP address before clicking Connect.
If you registered your domain name through your online store account, you’re done. The domain name is now set up with the correct IP address and a “wild card” A record that allows you to create subdomains easily. Your subdomain should start working shortly after you publish your website.
If the domain name was purchased through a different Square or Weebly account:
Log into your Square Online account that was used with the domain name.
Click the name on the upper right corner of the dashboard and select Domain.
Click on the domain name to open the settings.
Click Edit in the DNS Records section.
On the edit screen, click Add Record to add a new row at the bottom.
Choose A Record from the Type menu on the left.
In the Host box, type the subdomain you want to use. Don’t enter the full link here - just the first part (shop, for example).
In the Points to box on the right, paste in the IP address from the steps above.
Save andPublish your online store website when you’re ready to go live.
If your domain is registered somewhere else, log in to that account and create an A Record that points to the IP address from step one. The process should be similar to the steps outlined above, but each web host has its own set of instructions for creating a subdomain. If you aren’t sure what to do, you can ask the support team at your domain host, or check out these guides from some of the most popular hosts:
Note: Changes to domain settings can take up to 24-48 hours to begin working. If the new subdomain isn’t working right away, give it some time and check again. Most changes take effect within a short time.
