You can upload new coupon codes by following these steps:
Go to the All reports -> Coupon Lists
Сheck the description of a coupon list that needs to be replenished
Generate codes on your side with the relevant settings (discount value, min. purchase required, products specifications, etc)
Hit Add Coupons to upload new codes
Upload either a multi-line CSV file with a maximum of 100K rows (your CSV list should contain a header that specifies a column for coupon codes, or it should contain only one column with coupons and without a header) or list coupon codes manually
