Hello I am implementing a purchasing route through my app "Breathe ICELAND". Currently the app reroutes people to the Shopify checkout (which utilizes Rapyd as a purchasing method) but I want to allow them to complete their purchase within the app using Google Pay / Apple Pay.
As I understand this should work in tandem with my Rapyd purchasing service - but what I need to know is how I can get the Shopify merchant account to recieve Rapyd api calls with payment confirmation after Rapyd has charged the appropriate card / digital wallet, in order to complete the purchase of digital goods and send them using the shopify automatic email service.
Where in the API documentation can I find this specific information? Best
