Usage

To use the accept language middleware, register it with your application's middleware.

In Laravel 11 and newer, append it to the API middleware group in bootstrap/app.php:

In older Laravel applications, register it as a global middleware:

Register in a specific middleware group:

The middleware stores the full negotiation result on the request. This is useful for APIs that need to pick resource-specific translations instead of only setting Laravel's application locale:

You can also use the negotiator directly:

Use isAcceptedLocaleExcluded() when checking an explicit positive locale from acceptedLocales; it honors concrete q=0 ranges without letting *;q=0 reject explicitly accepted languages.

AcceptLanguageMiddleware adds Vary: Accept-Language by default. Disable this with automatic_vary_header if another layer owns response cache variation. When prefer_user_locale is enabled for authenticated APIs, make sure those responses are private/auth-aware in your cache layer because the resolved locale can also depend on the current user.

ContentLanguageMiddleware is available for single-locale responses. It will not overwrite an existing Content-Language header.
