# Multi-Language

Zotlo automatically adapts the checkout language based on the customer’s browser preferences. If the preferred language is supported, the checkout is shown in that language; otherwise, it falls back to English.

Multi-language support helps increase trust, reduce friction, and improve conversion in global funnels.

## **Language Selection**

* The user’s browser/OS language is detected automatically.
* If the language is supported, the checkout instantly switches to that language.
* If not supported, English is used as the fallback default.
* Merchants do not need to configure anything — language handling is automatic.
* RTL (right-to-left) languages are rendered with proper alignment.

#### Override Language

(Developer Use) If needed, you can manually force a specific language using [SDK parameters](/integrating-zotlo/web-sdk/sdk-overview.md) or [API fields](/integrating-zotlo/api-reference/introduction.md). Otherwise, auto-detection handles everything.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.zotlo.com/features/checkout/multi-language.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
