Hi
I’ve developed a payment app extension, when a payment request initiated from shopify checkout and land in to given redirect URL we need line item details to proceed. Shopify initiates an HTTP POST request to payment gateway that contains information about the customer and the order see sample request in this link Build an offsite payments extension with Shopify CLI
Obviously, no line items are included in the request, and that is what the payment gateway requires before it can redirect to the payment gateway page. How can I get the order line items?
