Essential Scripts and Whitelisted Domains Load Without Being Blocked by the Autoblocker

Updated

Data Processing Services (DPS), marked as essential, data-uc-allowed atributes, and whitelisted domains are never blocked by the autoblocker, keeping your site running smoothly from the first page load.

 

Before you begin, check the following:

 

Steps

  1. Log in to your Usercentrics Admin Interface
  2. Navigate to Configuration and select your active configuration ID
  3. Go to Data Processing Services. For any service that must load right away, make sure it is marked as Essential.
  4. For any HTML element you want to exclude from autoblocking, add the data-uc-allowed attribute directly to that element in your site's source code. <script data-uc-allowed src="..."></script>
  5.  Add a domain to the whitelist, navigate to Implementation > Script Tag > Blocking third-party script and add the domain to your Whitelist.
  6. Click Save Draft, then click Publish. Your changes will only take effect on your live site after you publish the configuration. 

 

What You Should See After

Once configured correctly:

  • Essential DPS loads immediately
  • data-uc-allowed elements are never blocked
  • Whitelisted domains load without delay
  • No interference from the autoblocker on these resources

Your site should behave consistently and reliably on first load.

 

If Something Isn’t Working

An essential DPS service is still blocked

Clear your browser cache and republish your configuration. Confirm the service is toggled as Essential and that the configuration is the active one on your site.

The data-uc-allowed attribute is not taking effect, and the element is still being blocked by the autoblocker

Make sure the attribute is written exactly as data-uc-allowed and applied to the correct HTML element. Even small spelling differences or incorrect casing will prevent it from working.

A whitelisted domain still loads late?

Make sure the domain is entered correctly in the Blocking third-party scripts section. Use only the base domain (no paths or trailing slashes). After updating, save your changes and republish the configuration.

Changes are not reflected on the live site

Make sure you click Publish after saving. Only published changes are applied to the live environment, saving alone won’t update your site.
