This option allows LinkTrust to append any additional data which was added to the affiliate's tracking link to the landing page URL.
Why would I enable this?
If you want any additional data appended to the affiliate's tracking link to be sent to the merchant on the landing page URL or the alternate landing page URL, enable the Propagate Additional Data option.
How do I enable Propagate Additional Data?
You can enable each campaign to individually allow the propagation of additional data in campaign settings. Click the box located directly beneath where you enter your default landing page URL.
Why would I disable this?
If you want to block any appended data from being added to the landing page URL or the alternate landing page URL location, disable the Propagate Additional Data option.
Additional Data is any name=value pair that has been added to the Tracking URL or Merchant's Pixel URL which is not used by LinkTrust. When this additional data passes through LinkTrust, it is recorded and displayed for each transaction within the Transaction Details Report. The ability for an Affiliate to pass additional data through LinkTrust can be limited. By default, LinkTrust doesn't allow additional data on a Tracking URL to be passed to the Merchant's landing page.
If you wish to pass the CID, AFID, SID or ADID, add a token for the appropriate value you wish to pass.
Additional Data Tokens
If you wish to place a token that provides a specific value from an Affiliate's Tracking URL or a Merchant's pixel URL, place [= and =] around the name of the field that was provided on the URL. For example, if your affiliate appended "&site=google&type=search" onto their Tracking URL, You can pass either of these values back onto their tracking pixel by adding "&site=[=site=]&type=[=type=]".
