A custom domain changes recipient-facing HummingDeck URLs from the standard host to a branded subdomain such as docs.yourcompany.com.
You request the subdomain in Workspace settings, and HummingDeck Support completes the setup. Do not add or change DNS records until Support sends the records for your workspace.
Custom Domain
Use your own subdomain for share links (e.g., docs.yourcompany.com)
After you send the request, we'll email you the DNS records to add. Most setups are completed within one business day.
Root domains (e.g., yourcompany.com) are not supported. Please use a subdomain.
Choose the subdomain
Use a subdomain that recipients will recognize, such as docs.yourcompany.com or deals.yourcompany.com. Root domains such as yourcompany.com are not supported.
Before requesting setup, confirm:
- you or a colleague can edit DNS for the parent domain;
- the preferred subdomain is not already used by another service;
- your team knows whether any existing branded links need to keep working.
Send the request
Open Workspace, scroll to Custom Domain, enter the subdomain you want, and select Request Domain. Sending the request is one step: it opens a support ticket for you, so there is nothing to write.
Only the workspace owner can send the request.
Wait for the DNS instructions
Support checks the workspace and domain, then replies by email with the exact records to add: a CNAME that routes the subdomain to HummingDeck, and a Google verification record that authorizes the certificate. Expect that message within one business day.
Add both records with your DNS provider, then reply to the same ticket when they are in place.
Do not add DNS records before Support sends them, and do not reconstruct records from another workspace or an older setup. Hostnames and verification values differ per domain.
Let Support complete the setup
Support verifies the DNS records, completes routing, and provisions SSL. DNS and certificate changes are not always immediate, so wait for confirmation before sharing recipient links on the new domain.
If the records cannot be verified, send Support a screenshot or copied view of the DNS entry. Remove account identifiers, unrelated records, and any secret values before attaching it.
Test the recipient experience
After Support confirms that the domain is active:
- Open a document link on the custom domain in a private browser window.
- Open a Room link on the custom domain.
- Test the access mode you normally use.
- Check downloads and any HTML content you plan to share.
- Confirm that the browser shows no certificate warning.
Change or remove a domain
Remove in the Custom Domain section clears the domain from the workspace, including a request that has not been completed yet. It does not delete DNS records you already added.
Contact Support before changing or removing a domain that is already active. Existing branded URLs may stop working, so Support can help plan the transition and confirm when replacement links should be sent.
