Hi everyone,

Now I have an app and it has a feature that collects payments of orders from Shopify. But I don’t know how to categorize the payments correctly.

Here are my questions:

Question 1: Using Processing Method or Payment Gateway? what is better?

OR

- Question 2: Do you know what payment gateways will be categorized in what processing methods.

I ask this question because sometimes, direct providers are still categorized in processing method "Check out. Is that right?

Really appreciate everyone’s help!

Best regards,

Can anybody answer my questions?

No, anyways…
