With a custom domain, the application links your participants receive live on your own subdomain, for example https://onboard.yourcompany.com/apply/abc123 instead of https://app.klara-ai.com/external/your-org/apply/abc123. Everything participants see stays on your branded host, including email verification and returning visit sessions.
Custom domains are enabled per organization. If you don’t see Custom Domain under Settings, contact your account manager or hello@lissom.ai to have it enabled.

​
Prerequisites

  • Custom domains enabled for your organization
  • Admin access to your Lissom dashboard
  • Access to your company’s DNS settings
  • A subdomain to dedicate to Lissom (e.g., onboarding.yourcompany.com or kyb.yourcompany.com). Apex domains like yourcompany.com are not supported.

​
Setting up your domain

1

Enter your subdomain in Lissom settings

Go to Settings → Custom Domain and enter your desired subdomain, e.g. onboard.yourcompany.com. Provide the hostname only. No https://, paths, ports, or query params. Only subdomains are supported; apex domains like yourcompany.com are not.
2

Lissom shows the DNS record to add

Lissom validates the domain and shows the DNS record you must add, for example:In some cases an additional TXT record is required to prove domain ownership, if the dashboard shows one, add it too.
3

Add the DNS record

Add the record wherever you manage DNS for yourcompany.com.
4

Verify

Click Check DNS. Lissom checks that onboard.yourcompany.com resolves to the expected target, DNS changes can take a few minutes (occasionally longer) to propagate. Once verified, Lissom provisions TLS automatically so the domain works over HTTPS. No certificate management is needed on your side.

​
Lissom handles the rest

Once the domain is Active:
  • New application links use your custom domain: https://onboard.yourcompany.com/apply/{token}. This applies to links returned by Create Application and Refresh Pre-Auth, and to invite and reminder emails.
  • When a user opens the link, Lissom’s edge layer handles it internally and serves the Lissom-hosted application — nothing to deploy or proxy on your side.
  • Existing links keep working. Previously issued app.klara-ai.com/external/... links remain valid indefinitely, there is no redirect or cut-over to worry about.
  • The participant experience is unchanged. Email verification, pre-auth codes, saving progress, and returning visits all work on your domain exactly as they do on the default host.
Your dashboard, API endpoints, and webhooks are unaffected, the custom domain only serves participant-facing application pages.

​
Limits

  • One custom domain per organization.
  • Subdomains only, apex/root domains (e.g., yourcompany.com) aren’t supported.
  • The domain must not already be in use by another service.

​
Troubleshooting

Removing the domain from the dashboard reverts all new links to the default lissom.ai host immediately.
