About the Stonewren: Bulk Discount Codes

Generate thousands of unique discount codes in bulk instead of creating them one at a time in Shopify. This app lets you create up to 100,000 single-use discount codes per batch, perfect for printed inserts, events, influencer campaigns, and refer-a-friend programs. Each code is limited to one use per customer, preventing shared codes from being passed around online. Batches show live progress and retry automatically, so nothing fails silently. You can import your own codes by paste or export everything as CSV or XLSX files. The built-in API and webhooks let you connect your other tools to create sets and pull fresh codes automatically. Set expiry dates, usage limits, and custom prefixes or suffixes. All codes skip look-alike characters like 0, O, 1, I, and L to prevent customer typos.
