Here is a breakdown on to to set and modify the expiration time of a discount code.

After each purchase, Duo automatically generates a unique discount code for the customer to share. When this code is redeemed by a new customer, the original customer earns cashback. Learn more about the Duo lifecycle. To ensure engagement and drive timely referrals, these codes have a limited validity period.

1- To set the expiration time for your referral codes, simply navigate to the "Referral Program" section in the Duo app.

2- You can then choose the timing that suits your brand the most. We encourage our users to set an expiration time of more than 48h.

Once you have set up your duration to invite, you can add new rewards per order value ranges in the reward tab to select rewards depending on your profit margins.
