Blocking with a single GTM event

sp-consent="PLUGIN NAME"in the field “Event name”. (The correct plugin/service name should be copied from your scan report page inside Secure Privacy account under the "Classification" tab)
If you are blocking Google Analytics, your configuration should look like this. We have named the trigger as SP-Consent-Google-Analytics
Enter: sp-consent="Google Analytics"
Click “Save” to create the trigger.
Repeat the above for each type of plugins, so you have all triggers created on your GTM.
Now that you have created your Trigger, you need to attach it to their respective Scripts.
Your Next steps will depend on the Plugin which you need to block. In this article, we are taking Google Analytics as an example.

As a trigger, select the trigger you have just created, “SP Consent-Google-Analytics”. Click “Save” to create or update the tag.

Finally, click “Publish” to push your changes live to your site.
