How to define a custom domain for your user portal for Trello
Using a custom domain allows you to present your User Portal with a branded URL instead of the default Hipporello address.
Setting Up a Custom Domain
Open the Hipporello Power-Up from your Trello board
Navigate to Hipporello Admin → User Portal → Domain Configuration
Click + Add a Custom Domain
Enter your preferred domain (for example: support.yourcompany.com)
Click Add

Configuring DNS Settings
Log in to your DNS provider
Create a CNAME record
Copy the CNAME value provided by Hipporello
Save the record
If requested, set the TTL value between 30 minutes and 1 hour, or leave it blank.
Domain activation may take up to 24 hours after DNS propagation.
