Enable Promo code and choose a mode: Same for all (one shared code) or Unique code per creator. For unique codes, add them manually per creator, or upload a CSV — either auto-attributed (a code column, assigned automatically) or pre-attributed (code and creatorId columns). Attribute missing codes assigns available codes to confirmed creators who don't have one, and the attribution modal shows how many codes exist, how many are unassigned, how many confirmed creators still need one, and what to do about it.

Codes are only visible to creators who have accepted the campaign.
