Checkout Language

The checkout page language is determined dynamically based on the customer's preferences and system configurations. This ensures a seamless and personalized user experience. The language is chosen in the following order of priority:

1. Browser cookies: Uses the lang cookie value if available.
2. lang parameter sent via API: Overrides the cookie value if specified.
3. Browser language preferences: Acts as a fallback if no cookie or lang parameter is provided.

Language Selection Priority

1. Browser Cookies

The lang cookie stores the customer's preferred language for the checkout page. If the cookie exists, the checkout page uses its value to set the language.

2. Define the Checkout Language

If the lang cookie is empty or not set, the lang parameter provided in the API request determines the checkout page's language. You can use this option when using any of the Fondy solutions. This option is useful for custom integrations or scenarios where the API dictates user preferences.

The following code block shows how to set the langparameter.

POST /checkout
Content-Type: application/json

{
  "lang": "fr"
}

In this example, the checkout page will display the content in French (fr).For more details on sending the lang parameter via API, refer to the Accept Purchase documentation🡥.

3. Browser Language Preferences

If neither the lang cookie nor the lang parameter is set, and the checkout page defaults to the browser's language preferences. The browser automatically applies the language set as the default preference in its settings. For more information, access Setting language preferences in a browser🡥
