PartnerStack parameter
What is the ps_xid parameter?
ps_xid is PartnerStack's partnerstack session id. ps_xid is the click/session identifier that pairs with ps_partner_key to bind a signup to your specific referral click in PartnerStack.
Where it appears
In your link AND it must survive to the final page
Example
https://vendor.com/?ps_partner_key=AbCdEf123&ps_xid=xyz789If ps_xid is missing
ps_xid travels with ps_partner_key; its absence matters when the partner key is missing too.
How PartnerStack tracking fits together
PartnerStack tracks via parameters on the vendor’s own domain (or a vendor-branded go-link that redirects there). The PartnerStack script on the vendor site reads ps_partner_key / ps_xid and attributes the signup, with server-side tracking backing it up.
SaaS marketing sites get rebuilt constantly — new domains, new landing paths, new signup flows. Each rebuild is a chance for old partner links to lose their parameters or land on retired pages.
