Updating OneTrust for Consent Mode V2

Depending how you have installed your OneTrust banner, will determine what update if any you need to make to be prepared for consent mode V2 changes. It is important to have this correct or else it can impact your data tracking to all platforms.

First, let's determine how you have installed your banner

Click on the One Trust tag visible to you from the list. Check if your OneTrust tag in Google Tag Manager has a data domain script section visible like this in the following screenshot or not.

Setup Type 1

Setup Type 1

If your OneTrust Tag setup is looking like this (above) with the “Data Domain Script” section visible with a code or any text, you are using Setup Type 1 with your banner added via GTM


Setup Type 2

Setup Type 2

If you can not see the “Data Domain Script” section visible in your tag (above screenshot), you are using Setup Type 2 with your banner hard-coded in your site code or theme file.
