2. RewriteRule ^shippingoptions$ index.php?route=extension/payment/kustom_ssc/shippingoptions [L,QSA]
3. RewriteRule ^shipment$ index.php?route=extension/payment/kustom_ssc/shipment_create [L,QSA]
4. RewriteRule ^shipment/([^/]+)$ index.php?route=extension/payment/kustom_ssc/shipment_item&shipment_id=$1 [L,QSA]

In the Kustom/Klarna Shipping Assistant panel set:

Base URL = your shop domain (or with the prefix used in the rewrites).

The related endpoints will therefore be:

• /auth
• /shippingoptions
• /shipment
• /shipment/{id}
• /shipment/{id}/confirm

Selling in Multiple Countries

Kustom Checkout is available in 229 countries, with more than 10 considered core countries, including support for Kustom Credit, local cards, and alternative payment methods.

Core Countries and Supported Currencies

Note: Kustom does not support currency conversion. Orders must be managed in the same currency as configured in the Kustom Order Management API.

⚙️ Integration Recommendations

• One URL per market (e.g., merchant.co.uk): set purchase_country = GB.
• One URL for multiple markets (e.g., merchant.eu): enable all supported shipping countries and use the country_change callback to update language and currency.
