Zoho Desk domain mapping lets you serve your help center or customer portal from a URL you control instead of a zoho.com address. That gives a branded, consistent support URL and lets you verify ownership and manage DNS records through your domain registrar or Zoho Directory.
What is it
Domain mapping in Zoho Desk connects a custom domain or subdomain (for example, support.yourcompany.com) to your Desk help center or portal so customers reach your branded site instead of a Zoho-hosted URL. It requires you to add DNS records at your domain registrar (usually a CNAME) and verify the domain in Zoho so SSL and routing can be configured. After mapping, the portal displays under your domain and keeps Zoho Desk functionality like articles, tickets, and user sign-in intact. Several Zoho apps use the same pattern for portal-level custom domains, so the steps and requirements match other Zoho products. [8][1]
When to use it
- You want your help center URL to match your corporate brand (for example, support.yourcompany.com instead of desk.zoho.com). [8]
- You run multiple regional or product portals and need separate subdomains for each (for example, eu-support.yourcompany.com and us-support.yourcompany.com). [4]
- You must remove visible Zoho branding from customer-facing support pages and present a white‑labeled experience. [7]
- You need a stable URL for integrations, web widgets, or single sign-on that reference your company domain instead of a Zoho-hosted address. [2]
- You already manage domains in Zoho Directory and want the mapped domain to appear and be reused across other Zoho apps (mail, Creator, Backstage, etc.). [4]
How to access it
Open Zoho Desk and go to Setup (gear icon). Look for Portal or Help Center settings under Portal Configuration or Portal Settings and choose the Custom Domain / Domain Mapping option to begin mapping a domain. The UI will prompt you to enter the domain and show the DNS records you must create (CNAME or verification TXT) at your registrar; domain verification can also be completed through Zoho Directory if you manage domains centrally. Exact labels vary by product and plan, but the path follows the same Portal Configuration > Custom Domain pattern used across Zoho apps. [1][8][4]
