UTM codes that are defined in URLs are only used by Google Analytics and are not recorded in Luminate Online. Luminate uses a similar feature called Source Codes to help report on where/how users found a certain page in your site. You can either specify the source code in the URL, or you can specify a default source code within the configuration of a donation form, survey, etc.

How do I manually set the source code and sub-source code for a link?
