Reserve words so partners can't give their links names that look like yours, such as ?via=acme or ?via=google. A partner can't name a link exactly one of your reserved words.
Available on Pro and higher plans.
Go to Program settings › Tracking.
Under Referral links, click the Reserved words field.
Type a word and press Enter. Repeat for each word you want to reserve.
Partners can no longer give their links any of the reserved words as a name.
Good to know
Only exact matches are blocked. Names that contain a reserved word, like acme-deals, are still allowed.
You can reserve up to 50 words. To remove one, click the ✕ next to it.
Reserved words only matter while partners can create their own links. See Stop partners from creating links.
