I have an APP in APP store that works with Strip. If I want to run this APP in some countries like IRAN for example, how would I know if the credit card works for payment processing? Please advise.
Considering that you have mentioned Stripe as your payment processor, the best way to check this will be to see if Stripe works in Iran. If they do, credit card payments through the app will work in Iran. You can reach out to Stripe from https://support.stripe.com
