How to call getSellerProfiles in Ebay API?

Question

PHP

Tell me how to call getSellerProfiles in the Ebay API?
I try using standard methods, like all other requests, to execute using PHP

$xml='<?xml version="1.0" encoding="utf-8"?>';
  $xml.='<getSellerProfilesRequest xmlns="urn:ebay:apis:eBLBaseComponents">';
    $xml.='<RequesterCredentials>';
      $xml.='<eBayAuthToken>'.$data_user['ebay_token'].'</eBayAuthToken>';
    $xml.='</RequesterCredentials>';
    $xml.='<profileType>PAYMENT</profileType>';
  $xml.='</getSellerProfilesRequest>';
  $headers=array(
    'Content-Type: text/xml',
    'X-EBAY-API-COMPATIBILITY-LEVEL: 1085',
    'X-EBAY-API-DEV-NAME: '.$data_dev['ebay_dev_id'],
    'X-EBAY-API-APP-NAME: '.$data_dev['ebay_app_id'],
    'X-EBAY-API-CERT-NAME: '.$data_dev['ebay_cert_id'],
    'X-EBAY-API-SITEID: 0',
    'X-EBAY-API-CALL-NAME: getSellerProfiles'
    );
  $ch=curl_init();
  curl_setopt($ch,CURLOPT_URL,"https://api.ebay.com/ws/api.dll");
  curl_setopt($ch,CURLOPT_HTTPHEADER,$headers);
  curl_setopt($ch,CURLOPT_POSTFIELDS,"xmlRequest=".$xml);
  curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);
  curl_setopt($ch,CURLOPT_HEADER,FALSE);
  curl_setopt($ch,CURLOPT_POST,TRUE);
  curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,FALSE);
  curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,30);
  $content=curl_exec($ch);
  curl_close($ch);
  $obj=simplexml_load_string($content);
  var_dump($obj);

in response to me The API call "getSellerProfiles" is invalid or not supported in this release.
there are no examples in the official description of the API on Ebay, I indicated everything by analogy with other examples that work properly ...
What could be the problem?
Ps - I searched in the search engine and did not find anything useful ...
