Global eCommerce: Full-Cultural Context Translations

We want to implement an automatic translation system in our e-commerce using the DeepL API, combined with the user's geolocation. The idea is that, when accessing the website, the language is automatically changed according to the customer's location. The flow should be as follows:

User Location Detection:

Use a geolocation API, such as ipinfo.io or GeoIP, to detect the user's country based on the IP address as soon as they access the website.

Language Mapping by Country:

With the user's location identified, the system should map the country to the corresponding language. For example:

Argentina → Spanish

Brazil → Portuguese

Germany → German

United States → English

If there is no corresponding language for a given country, the system should apply a fallback to English (or another default language).

Content Translation with DeepL:

For dynamic website content, use the DeepL API to automatically translate the texts into the identified language. If the site already has pre-translated versions, the system must redirect the user to the correct version.
Preference Storage:

Implement the use of cookies to store the user's preferred language choice, so that on subsequent visits the site is already in the correct language, without the need for new detection.
Fallback in Case of Error:

If localization detection fails or the language is not supported, ensure that the site appears in the default language (such as English).
