1. Visit Developers Console.
  2. In your project: Compute -> App Engine -> Settings.
  3. On the tab labelled CUSTOM DOMAINS, you can verify your domain and assign it and/or its subdomains to your GAE project.
  4. Add the DNS settings provided by Google into the DNS server of your domain provider.


  1. Only HTTP is supported, HTTPS is not.
  2. It will not work if you only modify the DNS record without actually assigning the custom domain in the Developer Console.
