Adding a Custom SSL configuration

If you cannot or do n'ot want to use Content Delivery Networks when setting up SSL for click and open tracking, you can set up a custom SSL configuration.

Before Adding a Custom SSL configuration, you need to set up a valid link branding on your account.

To add a custom SSL configuration:

  1. Prepare a proxy (like a web application, NGINX, or Amazon API Gateway) to take all traffic for and forward it to or
  2. Set up the proxy to use HTTP or HTTPS. For HTTPS, provide a valid SSL certificate for domain.
  3. To forward traffic, set the Host HTTP header to domain.
  4. Point the CNAME record to your proxy. For example, CNAME

Do not validate the DNS record more than once. After changing the CNAME, a second validation will fail, and the authentication will stop working.
