DESCRIBESProblem

I am not able to find an API that validates whether a customer has already redeemed a given promocode. — I have created promocodes for discounts, which can only be redeemed once per customer. Tension: I want to validate whether a given customer has already redeemed a specific promocode. Outcome: If they haven't redeemed it, I want to proceed to the next step; otherwise, I want to stop the customer at that point.
