1. Create a Coupon

When you are creating vouchers that are only allowed to be redeemed once you need to create a new coupon and choose the “One-time Redeemable” type.

In the next step, you need to create a set of unique QR Codes. This is done by “Create Bulk Vouchers” in the redeem section like shown below:

3. Download Vouchers

When downloading the QR Codes select your format. We recommend you use a vector format like EPS or PDF for printing. Also set the Error Correction Level to L, which allows you to print the QR Codes in a smaller size.

MailChimp Integration

Voucher per Subscription

If you want to provide a unique coupon to a user when he subscribes to a MailChimp mailing list you can automatically do this by connecting MailChimp with our platform through a Webhook.

After a new user confirms his subscription in MailChimp he will receive a mail with a link to the one-time redeemable voucher.
