Redirect URLs

When you connect Supabase through Noah, redirect URLs for Noah’s default domains are automatically configured — no manual setup is needed.

However, if you use a custom domain for your published app, you will need to add it as a redirect URL in Supabase manually. Without this, authentication links (confirmation, password reset, magic links) will not work on your custom domain.

When Do You Need This?

You only need to update redirect URLs if you are using a custom domain (e.g., https://app.yourbrand.com). If your app is published on a default Noah domain (*.app.trynoah.ai), everything is handled automatically.

Add Your Custom Domain as a Redirect URL

1. Open the Authentication settings

   In your Supabase dashboard, go to the Authentication section in the left sidebar.

2. Go to URL Configuration

   Under CONFIGURATION, click URL Configuration.

3. Update the Site URL

   Replace the default http://localhost:3000 with your custom domain. This is the fallback redirect when no other URL matches.

   For example: https://app.yourbrand.com

4. Add your custom domain to Redirect URLs

   Under Redirect URLs, click Add URL and enter your custom domain. Wildcards are supported.

   For example: https://**.yourbrand.com**

5. Save changes

   Click Save changes to apply the new configuration.

   

Troubleshooting

Link still goes to localhost

Clicking a confirmation or reset link opens localhost:3000 instead of your custom domain.

• Double-check that the Site URL field is set to your custom domain and begins with https://
• Remove any trailing slashes — they can interfere with redirects

Link opens the app but user is not logged in

The link loads your app, but the user is not authenticated.

• Make sure the redirect URL exactly matches your custom domain, including protocol (https://) and no trailing slash
• Confirm your Noah app is connected to the same Supabase project where the URL is configured
