Hey folks,
I have been developing an app lately but am stuck with this question. The one time charge for the app will work fine with the Shopify API what if I wanted to provide add-on(additional) services through the app that would require an additional charge. Can add-on charges be made through the Shopify API in the app once it's active in the owners store? I know I can easily do it by taking payments for add-on services through external forms but what if I wanted to do it through the Shopify API.
Would appreciate any help.
Cheers.
