To enable us to create your branded link for your app you will require your own domain.
If you do not have a domain, they can be purchased from sites such as GoDaddy or 123Reg.
To set up your custom app URL you will need to login to your website domain provider and go to your advanced DNS settings, add a new CNAME Record and set the below:
HOST: app
CNAME Record: cms.appbuild.io
TTL: Leave as default
Once your CNAME record is set with your domain provider, go to the Marketing section within the AppBuilder, select App URL and enter your domain name in the section provided.
Your new app URL will be available in the following format:
app.yourdomainname.com/app/appcode
Please be aware that whilst most domain providers propagate instantly, some take between 24-48hrs.
