01 Stage 1
Your existing links keep working, after one change
Two answers, depending on the link.
A direct Trackdesk link lands on your own site. It carries three tags: sourceId, linkId and tenantId. The first one is the affiliate, written the way you named them. We asked Trackdesk's own API to build a real link on 9 September 2026. It answered yoursite.com?linkId=lp_884203&sourceId=alex-stone&tenantId=yourprogram. Those three names are fixed, and nothing in Trackdesk renames them.
So those links keep paying. Run the import, then copy your tracking tag again. The new tag reads sourceId, and every link your affiliates already shared still credits the right person.
The other kind redirects through trackdesk.com first, and lands with a click id. Nothing on your site can turn a click id into a person, so those affiliates get a new link (their help centre, checked 3 September 2026).
Said plainly
Look at a link one of your affiliates shares. Does it start with
trackdesk.com, or with your own domain?Your own domain, with
?sourceId=martaon the end: that keeps paying. The import sets your tracking tag up to read it.trackdesk.com: that link carries a click id. A click id names one visit inside Trackdesk, not a person, so it credits nobody. Those affiliates get a new link from the AffiliateRail portal.Most programs have both. Stage 3 is the month that makes the swap painless either way.
