Allow a locale parameter in the checkout request body so developers can set the checkout page language per transaction instead of relying solely on browser auto-detection or the store’s default setting. This enables serving buyers in their preferred language.
Or a solution would be to simply auto detect based on IP and serve checkout language based on that.

Thanks for the suggestion! You can already set the checkout language using the locale attribute on the Tebex.js web component.

If you’re looking for automatic language detection beyond browser defaults, feel free to leave that as a separate suggestion, and we’ll track it.
