How to Connect a Custom Domain to Power Pages

Connecting a custom domain to your Power Pages website makes your site look more professional and brand-friendly. Instead of using the default powerappsportals.com URL, you can use your own domain like www.yourcompany.com.

In this blog, we’ll walk through the complete process of connecting a custom domain in Power Pages, including SSL (.pfx) upload and CNAME configuration.

Prerequisites

Before you start, make sure:

• Your Power Pages site is in a Production environment
• You own a custom domain (GoDaddy, Namecheap, etc.)
• You have a valid SSL certificate (.pfx file)

Custom domains are supported only in Production environments, not Sandbox or Trial.

Step 1: Open Power Platform Admin Center

• Go to the Power Platform Admin Center
• Click on Environments
• Select your Production environment

Step 2: Navigate to Power Pages Sites

• Inside the selected environment, click Resources
• Select Power Pages sites
• Choose your Power Pages website

Step 3: Click on “Connect Custom Domain”

• After selecting your Power Pages site
• Click on Connect custom domain

• This will open the custom domain configuration wizard

Step 4: Upload or Select SSL Certificate (.pfx)

To secure your custom domain, Power Pages requires an SSL certificate in .pfx format.

Option 1: Upload a New .pfx File

• Upload your .pfx file
• Enter the certificate password

Option 2: Use an Existing Certificate

• If a certificate is already uploaded, simply select it from the list

If you don’t have a .pfx file yet, you can generate one using OpenSSL.

Step 6: Add Host Name (Custom Domain)

After uploading or selecting the SSL certificate, the next step is to add your host name (custom domain) in Power Pages.

• Enter your custom domain name, for example:
  • www.yourdomain.com
  • portal.yourdomain.com
• Now Power Pages will check whether a CNAME record already exists for this domain.

If the CNAME Is Already Added

If you have already created a CNAME record in your domain provider that points to your Power Pages site:

• Simply enter the host name here

• Click Next / Verify
• Power Pages will automatically validate the domain

No additional DNS changes are required in this case.

If the CNAME Is NOT Added

If the CNAME record is not yet configured, you must add it in your domain provider’s DNS settings.

Power Pages will show you the target URL, which usually looks like this:
yourportalname.powerappsportals.com

Go to your domain provider (GoDaddy, Namecheap, etc.) and add a CNAME record with the following details:

• Type: CNAME
• Host / Name: www (or your subdomain)
• Points to / Value: yourportalname.powerappsportals.com
• TTL: Default

DNS propagation can take 15 minutes to 24 hours.

Step 7: Verify and Complete Setup

• After adding the CNAME record
• Go back to Power Pages
• Click Verify
• Once verified, the custom domain will be connected successfully
