This article describes how to set up the Epsilon Site Tag in your Tealium iQ Tag Management account.

Tag Configuration

First, go to the tag marketplace and add the Epsilon Site Tag (Learn more about how to add a tag).

After adding the tag, configure the following settings:

  • Domain and Tag Path: The domain to be used within the tag. Refer to the tagging document provided by Epsilon.
  • Reverse Proxy Directory Path: If you are using a Reverse Proxy, enter the path of the Reverse Proxy (typically /tag_path or the custom path you have setup as the root of your Reverse Proxy).
  • Company ID: dtm_cid
  • Secondary Company ID: dtm_cmagic
  • Form ID: dtm_fid
  • Integration Type: Default or Limited. Limited integrations should only be used if specified by Epsilon.
