How influencer promo codes actually work

The chain, step by step

1. The brand creates the code in their commerce platform and ties it to a discount rule: percent off, fixed amount, free gift, or free shipping.
2. The payout gets attached, or not. A commissionable code credits you per redemption. A discount-only code helps your audience and builds the relationship but pays you nothing directly; know which one you were handed. The taxonomy is in promo code vs affiliate link.
3. You distribute it: spoken in content, shown on screen, and parked somewhere copyable, because the code travels by voice and memory in ways links cannot.
4. Attribution happens at checkout. Affiliate networks treat unique codes as an attribution mechanism equivalent to a tracked link; ShopMy and Shopify Collabs both credit commissionable codes on redemption without any click.
5. Reporting flows back: the brand sees redemptions; you see whatever your program reports plus whatever you measure yourself, which is where copy counting earns its keep.

What makes a code deal good

• A code that is easy to say and hard to typo: short, no ambiguous characters.
• Commission attached to redemption, not only to clicks, so device switching cannot cost you.
• A stated expiry, and your card auto-pauses on it, so followers never chase a dead discount.
• Written terms: rate, cookie or window rules, exclusions, and whether coupon sites using your code strips your credit.

The creator's operational job

Once the brand mints the code, everything remaining is distribution and bookkeeping: keep every live code findable in one place, retire dead ones, and keep the numbers that prove your side of the deal. That job is what a code-first page exists for, and the multi-brand version of it is covered in organizing multiple brand partnerships.
