Step 1: Create a CNAME record within your DNS provider's administration panel, and configure it to point to your Desk.com host. For example, if your Support Center is http://yoursite.Desk.com, make your CNAME something like http://support.yourwebsite.com and point it to your Desk.com URL.
If you are not using Multi-Brand
This should look something like this:
support.yourcompanyisawesome.com CNAME yourcompany.desk.com
If you are using Multi-Brand
You will need to add an additional subdomain to your CNAME record. For example if you had two brands set up, one for support and the other for "VIP" support, your DNS record should look like this:
support.yourcompanyisawesome.com CNAME general-support.yourcompany.desk.com
vip-support.yourcompanyisawesome.com CNAME vip-support.yourcompany.desk.com
The first subdomain of the CNAME for a brand is arbitrary, but must be unique for each brand. For example, instead of "general-support.yourcompany.desk.com" you could use "tornadoes.yourcompany.desk.com" and it would work equally as well, provided that "tornadoes" is not already in use by a CNAME record for another one of your brands. In the "Custom Web Address" field for each brand (this is under Admin > Support Center > Advanced Settings) you would enter the URL that you specified in your CNAME record (e.g., "support.yourcompanyisawesome"). This can be a bit boggling, so please do not hesitate to reach out to your friendly Desk.com Support Team with any questions.
(Note: if you are changing an existing DNS entry rather than creating a new one, it may require some lead time before the change takes place, based on your DNS TTL (Time to Live). To minimize delays, we recommend reducing your TTL to 15 minutes at least 24 hours before you want to integrate your Desk.com Support Center. After your updates are complete, you can return to your regular TTL)
Step 2: Go your Admin Panel and click on Settings. It’ll take you to your Site Settings. From here, enter the domain you’ve decided on into the Web Address field:
Click Update, and your customization is complete.
