Collecting advertising ClickIDs is a use case related to affiliate and partnership campaigns.
Collecting the affiliate's click ID will allow you to return it to your affiliate platform via server-side API when attributing a conversion.
Collecting a ClickId involves integrating a dedicated parameter into the Eulerian URL used for ad click tracking. This parameter must be populated with the correct macro, which you can obtain from your advertising partner.
These parameters may change over time. Remember to have the parameter name confirmed by the advertising network before including it in your Eulerian tracking links.
