TYPES OF CUSTOM PAYMENT GATEWAY
Manual Integration
Third party agencies that provide custom Shopify development services can
manually host the app on their own server.
Pros:
This approach doesn’t need a post
development verification by
Shopify. A store can thus have a
payment service almost on the go.
Cons:
Being integrated manually, the
application is not hosted by
Shopify. As a result, marketing
the application will need mre
effort.
