I am sorry, I do not have any coding background, but I will try to explain to the best of my ability.
My store has been in existence for about 6 months and I want to target a different audience in Africa.
But, I am having a problem coding the payment processor API on Shopify.
Most of the countries use a Mobile Money wallet payment method from MTN and ORANGE
Here is a link to the MTN API Documentation.
Thanks for taking the time to read.
