Language Localization

Language localization enables shoppers to view checkout instructions and cart totals in their local language. This feature is disabled by default.

Configuration Options

There are two ways to define localization settings for Bolt Checkout:

  • Via Shopper’s Browser Settings (default)
  • Via injecting an ISO language code into the URL

Language Localization only applies to the Bolt Checkout experience; it does not override the language displayed by your site (such as product names, descriptions, or the shipping options). Numbers, such as product prices and cart totals, are localized.

ISO Method Options

For example, a shopper from Spain might search for “camiseta roja” (red t-shirt) and find a product page from the Spanish version of your site (e.g.,, or Without localization enabled, the checkout experience displays in English.
