What a link catches
The tap: which app it came from, which city, whether the person came back, and — on your own page — the pages visited and the order. Instant, per placement, live.
What a code catches
The person who saw a story, screenshotted it, and shopped from a laptop three days later. No link was tapped; the code at checkout still says who sent them.
Both, per marketer
Give every marketer a link and a code. On Shopmycode they sit on one line for that marketer, and a result carries one reward whichever was used — never two.
Discounts and rewards are different things
A code can carry a discount for the shopper and attribution for the marketer at the same time. Decide the discount from your margin and the reward from what a result is worth; the platform tracks the second, your store applies the first.
