Adds Klarna reference parameters for line items in Payment Intents

What’s new

Adds two fields for referencing transactions and subscriptions when using Klarna with Payment Intents for individual line items:

• reference: a reference number for this individual line item
• subscription_reference: a reference number for subscriptions in this line item

These optional parameters accept strings to provide item-specific references that Klarna uses for transaction processing and customer communication. These reference numbers are used for order tracking and customer support inquiries.

Impact

You can now provide transaction information to Klarna for individual line items. This improves the integration between your checkout flow and Klarna’s payment processing, and is used by Klarna to provide customer support and detailed transaction records.
