Is there a ready-made platform for a digital goods store?

Question

Online shopping

There are different keys for different products. Is there a ready platform/cms to sell them?
What should she do?
1. A person visits the site, selects a product (program, game, etc.)
2. Makes a payment through a card, i.money, qiwi (in general, through any electronic money or service, such as a robokassa, for example)
3. After payment is received by the product key, and if necessary (products are different) - a link to the distribution kit.
Since the key is a one-time thing, this key should not fall out to anyone else and should disappear from the system.
Of course, the free option (cms) is better, but if it is paid, then I want it to be not very expensive.

Answer 1

WordPress + WooCommerce. Woo has such a thing as a "digital good", plus it has a wonderful Robokassa plugin.
