Salesforce is built from the ground up to protect your data and applications. As part of our ongoing commitment to customer trust and security, integrations into Marketing Cloud Engagement are recommended to utilize tenant-specific endpoints for improved stability and scalability
As of the June, 2021 release, CloudPages began to migrate to newer, more secure URLs that use Tenant-Specific Endpoints (TSE) and away from the older Stack-Specific endpoints. Certain types of existing CloudPages URLs may be impacted by this change and will require update. CloudPages created and published after TSE-based URLs are enabled for the stack will use the new TSE-based URLs and will not be affected.
PLEASE NOTE: Although the new TSE-based URLs began rolling out in the June 2021 release, the old CloudPages URLs will still function by being redirected to the new URL. This redirect capability is a temporary service to allow impacted customers to change their old CloudPages URLs to the new TSE-based URLs.
Marketing Cloud Engagement automatically assigns a unique, system-generated subdomain to each of its tenants. A tenant represents your top-level Enterprise account and its business units, your Core account, your top-level Agency account, or your Client account, depending on your tenant type. Your subdomain is represented by a 28-character string starting with the letters "mc". When your subdomain is appended to Marketing Cloud Engagement APIs, it creates endpoints that are unique to your tenant.
You will want to locate any place that you have hard-coded your CloudPage URL and update it to the new URL, which can be found in the CloudPages app in the Marketing Cloud Engagement. A few examples of where you might have hard-coded a URL could be (but are not limited to):
Yes. While your page’s subdomain (pub) and domain (sfmc-content) aren’t changing, the string or GUID at the beginning of your URL will change.
If you’re using private domains for your CloudPages, nothing. You’re all set. Your pages will not be impacted with this change.
If you’re using the public domain URL for your CloudPages, after the redirect expires, any place where you have hard-coded the old URL will no longer redirect to the new TSE-enabled URL and your page will no longer receive that traffic. Users would see an error and would not be able to reach the CloudPage from that location.
