Generally, you can translate your checkout using langify.

Most Shopify themes already offer default translation for multiple languages out of the box. If that’s the case, checkout translations are already present, so you don’t need to do anything extra.

If your theme does not include built-in translations, you can translate the checkout by heading to langify -> Online Store -> Theme -> Shopify.

You can add the translations manually or by clicking the 'machine translations' button when you open the section.

Payment and Shipping options

These can be translated at langify -> General -> Shop -> Payment Gateway for Payment options, or Shipping and Delivery for Shipping options.

Unfortunately, custom shipping details cannot be translated in the Shopify checkout.

Custom Content Translations

Due to security restrictions during the payment process, langify is unfortunately not able to apply translations from the Custom section to the checkout.
