Tracking links can be customized with additional parameters that can be tracked by and reported to impact.com. These are called Sub IDs and Shared IDs. These parameters are useful when using various creatives, multiple websites, working with sub-affiliates, or in the case when you need to send non-PII customer IDs when linking users to advertisers. Many of these use cases require these parameters to be appended to tracking links in order to track and report this information accurately.
When a user clicks on an impact.com tracking link with Sub IDs (and/or a Shared ID) values appended, these parameters are captured by our tracking servers and stored. impact.com then correlates the click to the action. See the snippet below for an example of how these parameters are appended to a tracking link:

In the example above, the name portion refers to the parameter name being passed through and reported by impact.com in reporting. See the table below for additional details on the example link.
trackingdomain.net | The unique tracking domain provided by impact.com. |
mpid | Your Media Partner ID (MPID) |
adid | Assigned ID for the asset. |
campaignid | Assigned ID for the brand's campaign (view) |
The example below is what a tracking link with a Sub ID would look like. In this example, the value test will be passed when the link is clicked.
