Use Shopify Discounts or a dedicated app to create limited‑use unique codes

Discounty cannot create multiple unique codes or enforce a total-uses limit. To achieve 40 unique codes limited to 40 uses, use Shopify’s native Discounts or a third-party app: 1) Shopify Admin > Discounts: use the bulk/code generator or import CSV (or the ‘Create multiple codes’ option if available) and set usage limits; 2) Or install a dedicated app (e.g., bulk discount code generator apps) that can create many unique codes and enforce total/per-code usage limits. Refer to Shopify support or the chosen app’s documentation for exact steps.
