How to sell Pokemon Codecards with instant email delivery?

So, I would like to start a store that sells pokemon codecards that have instant email delivery.

However, I am unsure on how to enter the codes into the website and do instant email delivery when people buy one.

Also, I want to buy codecards so I would like to figure out how do do something like that.

Codecards basically are numbers you input into a game and you get virtual items within that game.

If I could have some assistance it would be great!

You’re probably going to need an app for that. Check the app store in the Digital Products category: https://apps.shopify.com/browse/orders-and-shipping-digital-products

Do you know any specific ones?

If you are buying and selling codes one-by-one and it’s not too time-consuming, you could embed each code into a text file and upload to an app like this one: https://apps.shopify.com/digital-downloads (I’ve used this and it’s pretty no-frills but it’s free, it works, and it’s developed by Shopify so it’s reputable.) If you have a ton of codes to enter and need a quick way to import them, then I’m not so sure. This one looks worth checking out but I know nothing about it: https://apps.shopify.com/foridev-selling-codes-app
