How to block a payment method for specific products

[Daniel71]

We would like to disable a specific payment method when specially tagged products are in the cart. The problem is that one of our external payment methods (Klarna) can only auth a credit card for 28 days, but in the case of items available for pre-order, the items might not become available for two months or more. So we would like to disable Klarna when the cart includes products that have specific tags. Is this possible? (note: we are a Plus store)

Hi @eitan_sperling -

Hiding a payment provider based on products in the cart can be done with custom Shopify scripts, see https://help.shopify.com/en/manual/apps/apps-by-shopify/script-editor, but custom scripts are only available for Shopify Plus merchants.  If you are Shopify Plus and need further examples or support, please let us know; you can open a support case with us by emailing: skosm@klarna.com
