Question.
1. how to make a translation of what the rest gives?
2. how to make a search in the rest, taking into account the fact that they enter something not on the sourceLanguage?

Answer 1

yii\rest\Controller has a ContentNegotiator filter, which also accepts the language in Yii::$app->language. Configure supported languages ​​via the container:

Yii::$container->set('yii\filters\ContentNegotiator', [
    'languages' => ['en', 'ru'],
]);

And send requests with the language:
The parameter name _lang can also be overridden.
