1. Have your IT department create a subdomain.
Once you’ve decided on the prefix to use for your custom domain, make a request to your IT folks to create a DNS record for your subdomain using the following fields:
Type: CNAME
Name: prefix.your_company.com
Value: app.slapfive.com
2. If your domain has a CAA record, override the CAA record for the subdomain.
If your domain uses a CAA record to allow Certificate Authorities to issue certificates, you will need to add a CAA record to the subdomain as follows. This enables SlapFive to create and maintain the SSL certificate.
prefix.your_company.com. 32 IN CAA 0 issue “letsencrypt.org”
3. Let SlapFive know that your CNAME record has been created.
We will create the SSL certificate and activate your subdomain in the SlapFive domain management console, then let you know when it is set up.
4. Enter your Custom Domain into your SlapFive Client Settings.
Go into Client Settings, and in the Custom Domain field, enter your custom domain, which is the Name field from your subdomain expressed as a full URL such as https://prefix.your_company.com.
5. Test the configuration.
Go to the Boards tab and open a board, make sure the Address shows your custom domain and that you don’t get any security warnings.
