Stamp

Promotions can be created as a stamp point promotion. The item specified in the promotion triggers one stamp point for each purchase. If the stamp points specified in the promotion are reached for the coupon, the coupon created in the promotion is played. Below is an example response in which the existing coupon was triggered by reaching the required number of stamp points.

The promotion includes a discount of €10.00 on the checkout process when 3 stamp points are reached
