Hi, did you find how to do ? I would like to sell vouchers on my e-shop and I'm looking for the best way to do it...

A digital product associated with a unique code, such as a license, or an unlock code. Only one product that sells a license. I can take the example of games on steam, where you redeem the game through a code.

Can you explain the escenario
