Domain Mapping

Estimated reading: 3 minutes 361 views

Zoho Desk domain mapping lets you use your own domain for customer support, instead of the default Zoho Desk subdomain (portalname.zohodesk.com/portal). For example, agents and customers could access support at support.mycompany.com, giving a more professional and consistent brand experience.

Before you start

  • Only users with the Support Administrator permission profile can configure domain mapping.
  • These steps apply to the agent interface and the default Help Centre only.
  • Third-party wildcard SSL certificates are not supported; Zoho Desk issues its own certificate.
  • Enable third-party cookies in your browser for the best experience, particularly on Safari.

1. Add a subdomain in your DNS

Create a subdomain, such as support.mycompany.com, then add a CNAME record pointing to the value Zoho Desk gives you: desk.cs.zohohost.com for accounts hosted in the US, desk.cs.zohohost.eu for the EU, or desk.cs.zohohost.in for India. DNS changes can take time to propagate.

2. Add the domain in Zoho Desk

  1. Go to Setup > Organization > Rebranding > Domain Mapping.
  2. Click Map Domain.
  3. Enter your domain URL, for example support.mycompany.com. It must not exceed 46 characters.
  4. Click Next.

3. Verify domain ownership

Verify using either the CNAME method or the HTML method.

CNAME method

  1. Use the unique CNAME code shown in the setup wizard and add it to your DNS records.
  2. Return to Zoho Desk and click Verify.

If you use Cloudflare, disable it temporarily during verification.

HTML method

  1. Download the zoho-domain-verification.html file from the wizard.
  2. Upload it to the root directory of your domain.
  3. Visit the file’s URL to confirm it’s accessible.
  4. Click Verify in Zoho Desk.

4. Get an SSL certificate

Click GET SSL in the wizard after verification. Zoho Desk generates and installs the SSL certificate; this can take up to 3 business days.

5. Apply the domain

  1. Once SSL is installed, return to the Domain Mapping page.
  2. Click Apply Domain next to your verified domain.
  3. Click Apply in the wizard.
  4. Click Visit Domain to test it, and refresh your browser to see the change.

Resetting or deleting a domain

To revert to the default Zoho Desk URL, go to Domain Mapping under Rebranding, click the Reset icon next to the domain, and confirm. An applied domain cannot be deleted until it has been reset; once reset, click the Delete icon and confirm to remove it.
