# Localization

Suppliers can store content in multiple languages in Ventrata. Requests should include the `Accept-Language` [header](https://docs.ventrata.com/getting-started/headers), ideally matching the language preferences sent by the client browser or user agent.

More information about the structure of that header is available on [MDN](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Language).

The API attempts to match the preferred languages against languages already translated by the supplier. The response includes a `Content-Language` header indicating the language returned, consistent with the HTTP standard.

Use the product operation below with the `Accept-Language` header to request localized content:

{% openapi src="<https://221588849-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M7bgGIyO7QYNOfUMfxh%2Fuploads%2Fgit-blob-fa2d8cb1d7297d352c2639e6c4c6a990f2add6d7%2Fopenapi.yaml?alt=media>" path="/products/{productId}" method="get" %}
[openapi.yaml](https://221588849-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-M7bgGIyO7QYNOfUMfxh%2Fuploads%2Fgit-blob-fa2d8cb1d7297d352c2639e6c4c6a990f2add6d7%2Fopenapi.yaml?alt=media)
{% endopenapi %}

The response `Content-Language` reflects the resolved language (for example English when no other translation exists):

If you cache content locally, use the `Octo-Available-Languages` header, which lists languages translated by the supplier.

You can repeat the request with each available language to retrieve localized content.

```

The question should be specific, self-contained, and written in natural language.
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.
