Stonewren: Bulk Discount Codes

Generate thousands of unique, single-use discount codes with CSV/XLSX export and an API.

Shopify lets you create one discount code at a time. It doesn't let you create ten thousand. Generate large batches of unique codes in a single run, each limited to one use per customer, so a code shared online can't be passed around. Batches retry automatically and show live progress, so nothing fails silently. Export to CSV or XLSX for printed inserts, events, influencer and refer-a-friend campaigns — or connect your own tools using the built-in API and webhooks.

• Generate up to 100,000 unique codes per set with live progress and auto-retries
• Import your own codes by paste; export everything as CSV or XLSX
• API & webhooks: create sets and pull fresh codes from your other tools
• One-use-per-customer, expiry dates, prefixes/suffixes, usage limits
• Codes skip look-alike characters (0, O, 1, I, L) so nobody mistypes them
