Configure SSL certificates and custom domain names

  • 5 minutes

When a portal is provisioned, it will have a portal URL that is a subdomain of powerappsportals.com, for example, contoso.powerappsportals.com. A common task for a portal administrator is to configure a custom URL for a Power Apps portal to reflect the domain naming conventions of an organization, such as https://www.contoso.com.

Note

You can have only one custom URL for each portal.

The following sections describe how to add a custom URL to a Power Apps portal.

Prerequisites

  • The organization needs to have a valid SSL certificate for the domain. The SSL certificate must be in PFX format, signed by a trusted certificate authority, and meet many other security requirements (see Add SSL certificates for the full requirements list).
  • The domain name needs to have a CNAME record set up in DNS pointing to the contoso.powerappsportals.com domain that was configured during the portal provisioning process.
  • The portal must be in Production mode (that is, not Trial or Suspended) when you're adding a custom domain.

To configure a custom domain name, open the Power Apps portals admin shortcuts page.

  1. Sign in to the Microsoft Power Platform admin center.

  2. In the left pane, expand Resources and then select Portals.

  3. Select the target portal.

  4. Select Manage at the top of the page.

  5. That will open the Power Apps portals admin shortcuts page.
