Below are instructions for S2S tracking:

1. When a user lands on your page, you need to capture the clickid, which is found in the refid parameter (unless changed to your specific subtracking variable). This is unique with each visit. You can capture the clickid from a query string parameter that we place in the URL when we send users to the destination.

Example: https://examplesite.com?refid=110097545FOF15329258649496722

2. Using the example URL from step 1, your server will capture the clickid. It should be changed in a programmatic process to look like this example when fired (in the sid parameter):
