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.
