Answer 1

You must indicate in the header the type of response to be received. This example should help you understand what is wrong and where to fix it:

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://fleet-api.taxi.yandex.net/v1/parks/driver-profiles/list",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS =>"{\n  \"limit\": 100,\n  \"offset\": 0,\n  \"query\": {\n    \"park\": {\n      \"id\": \"ee6f33c4562b4e1f8646d157bd70b2c4\",\n      \"driver_profile\": {\n      }\n    }\n  },\n  \"fields\": {\n  },\n  \"sort_order\": [{\n    \"direction\": \"asc\",\n    \"field\": \"account.current.balance\"\n  }]\n}",
  CURLOPT_HTTPHEADER => array(
    "Accept: application/json",
    "Content-Type: application/json",
    "X-Client-ID: API7-sandbox-client",
    "X-API-Key: FoquKQFW/WgvS/Kae/GheB/BdOtcvzSZLYrZv",
    "Accept-Language: ru"
  ),
));

$response = curl_exec($curl);

curl_close($curl);
echo $response;

Answer 2

You send an array, and Yandex expects JSON.
