Subdomains

Every Appspace gets a free subdomain on tolinku.com (e.g. my-app.tolinku.com). Subdomains work immediately with no DNS configuration, and they include SSL by default.

Adding a subdomain

Section titled “Adding a subdomain”

  1. Go to Domains in the sidebar.

  2. In the Subdomains section, enter your desired subdomain name.

  3. Click Add Subdomain.

Your subdomain is live immediately. Links like https://my-app.tolinku.com/your-route will start working right away.

Naming rules

Section titled “Naming rules”
  • Length: 3 to 63 characters
  • Characters: Lowercase letters, numbers, and hyphens
  • Restrictions: Cannot start or end with a hyphen
  • Uniqueness: Must not already be claimed by another Appspace

Some subdomains are reserved and cannot be claimed: app, www, cdn, edge, api, admin, blog, docs, mail, dev, staging, test, status, support, help, and others used by Tolinku infrastructure.

Subdomain limit

Section titled “Subdomain limit”

Each Appspace can have up to 2 subdomains. This exists so you can smoothly transition when rebranding:

  1. Add your new subdomain (e.g. new-brand.tolinku.com)
  2. Update your app’s Associated Domains and intent filters
  3. Start using the new subdomain for new links
  4. Old links on the previous subdomain continue to work
  5. When you are ready, remove the old subdomain

Removing a subdomain

Section titled “Removing a subdomain”

Click Remove next to the subdomain you want to delete. This is immediate, and any links using that subdomain will stop working.
