How to make json format in api?

Question

Yii

I have such a question in postman, I get a json response, but let's say when I open this page in the browser I get the xml format, should it be so or not?
In config/main.php

'components' => [
       ....
        'response' => [
          'formatters' => [
              \yii\web\Response::FORMAT_JSON => [
                  'class' => 'yii\web\JsonResponseFormatter',
              ]
          ]
        ],

I registered this, but I get xml in the browser, I wanted to understand maybe, and it should be if postman gives json format

When the browser makes a request to the server, it indicates which content types it prefers in the form of a header
. In the framework, REST controllers are configured for two data types - JSON and XML
. the browser has indicated it as the preferred one. If you want to leave only JSON, then reconfigure the controllers. And then even in the browser there will be JSON.
