The Sub ID is an optional alphanumeric value that an affiliate can append to their tracking URL. Generally, Sub IDs are numbers and letters or something that designates an affiliate or sub affiliate. Because traffic types are redundant, the Sub ID value is repetitive. This allows you to use reporting to identify which Sub ID is performing the best. The token [=SID=] is available in many areas and can be used to populate the Sub ID value.
To add a Sub ID to a tracking link, add &SID=Sub_ID_Here to the URL. You may add up to ten (10) Sub IDs to the tracking URL. When adding additional Sub IDs the format of the URL will separate the Sub IDs with commas.
Example: http://www.TrackingURL.com/click.track?CID=XXX&AFID=XXX&SID=value1,value2,value3,value4...
*Note: When affiliates are passing a SubID, the only accepted characters are alphanumeric and dashes. Failure to comply will result in your affiliates getting an error message when trying to pull their SID report. The maximum length of a SubID is 500 characters. You cannot pass GUIDs as sub IDs. LinkTrust recognizes GUIDs used as sub IDs and will remove them. If you wish to pass a GUID to a landing page, use Affiliate Reference ID.
