How can I implement payment in the application through the app store?

Question

iOS

Good day to all! Tell me good people, we have an application in which you need to make a payment. We wanted to implement it through apple pay, but it is supported only on devices from 6 and above. The question is - how can I implement payment through the app store in iPhone 5 versions? I just googled and didn't find any guide... Maybe someone faced such a task and can share a link to the material where you can read about it? Thanks a lot for your help!
