Domain & Email Sending Domain Authentication and Redirect Settings

This page explains how to configure your custom domain for the login screen and the post-login redirect URL. Both settings can be edited from the "Basic Settings" screen.

1. Domain & Email Sending Domain Authentication Settings​

Configure the domain used by your SaaS application. This is an important setting that is also used as the sender domain for the login screen and various notification emails.
Email sending domain authentication settings improve the delivery rate of notification emails and help prevent spoofing.

Setup Steps​

  1. Log in to the SaaS Development Console.
  2. From the side menu, select "Domain".
  3. Enter the domain name you want to use and complete the registration.

※ Please use a domain for which DNS configuration is possible.

Domain Input Screen

DNS Configuration​

After registering your domain, the following configuration information will be displayed at the bottom of the screen. Please add the specified records using your DNS service.

Domain Ownership Verification (CNAME)​

Register the displayed CNAME record in your DNS. This verifies ownership of your custom domain and provides a secure authentication screen.

Email Sending Domain Authentication (DKIM)​

Note

Email sending domain authentication configuration is required when using Google authentication or invitation features.
If you only want to set the login screen URL to a custom domain, email sending domain authentication configuration is not necessary.

Please register all email sending CNAME records (there may be multiple) displayed on the screen to your DNS.

Status Verification​

When DNS configuration is performed correctly, "Operating normally" will be displayed on the screen.

When email sending domain authentication (DKIM) is completed successfully, "Custom domain authentication email delivery is enabled" will be displayed on the screen.
However, email sending domain authentication (DKIM) configuration may take 1-2 days for DNS propagation. If it is not reflected immediately after configuration, please wait some time and check again.

Login Screen URL​

The registered domain will be used as the login screen URL in the format auth.domain-name.
This can be confirmed in the SaaS Development Console under "Authentication & Authorization" → "Authentication Details Settings" screen.

2. Post-Authentication Redirect URL Settings​

Specify the URL (such as your company's SaaS application homepage) where users should be redirected after login completion.

Redirect URL Settings Screen

Authentication information (tokens, etc.) will be passed to this URL.
You can use the SaaSus SDK to implement callback processing to receive authentication at this URL.
