I’m trying to get help with this exact issue. @KristiAtKlarna maybe you can help us? Thank you!
Topic summary
Core Issue:
Merchants need to disable Klarna (or other payment methods) for products with specific tags—particularly pre-order items that exceed Klarna’s 28-day authorization window.
Solutions by Store Type:
For Shopify Plus merchants:
- Use Shopify’s Script Editor app to write custom scripts
- Klarna provides specific code examples in their merchant guide documentation
- Contact Klarna support (skosm@klarna.com) for implementation assistance
For non-Plus merchants:
- Originally no native solution available (Shopify doesn’t support checkout customizations on basic plans)
- As of 2024, third-party apps now enable this functionality:
- BeSure Checkout Rules
- PayRules: Hide Payment Methods
- Bony: Checkout Rules & COD
Implementation Process (via apps):
- Create a “hide payment methods” rule
- Set condition based on product tags
- Select which payment method to hide (e.g., Klarna)
- Payment method automatically hides only when tagged products are in cart
Limitation Noted:
One user reported that blocking a gateway via script doesn’t prevent it from appearing as an “Express Checkout” option on the first checkout screen.
