How to send Line Item information to payment gateway

[Hancil]

Hi,

I am building an app that provides subscription features for the product. Currently, I am facing some issues in getting data of subscription-related information that is provided in the cart. I'm using ln using line items properties to store this additional data in the storefront UI code. These line items data can be seen when I navigate too the product information page and shipping details page but I am not able to get this data in the backend of the payment provider.

Let me know what approach I need to take here.

Thanks,
