Как авторизоваться на target.com с PHP?

Question

[Сергей Дружко]

Что только не перепробовал что-бы авторизоваться на target.com... - всё четно.

<?php 
	function clrequest($url, $postdata = null, $cookiefile = 'tmp/cookies.txt')
	{
		$ch = curl_init($url);

		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
		curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
		curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0');

		//curl_setopt($ch, CURLOPT_PROXY, '192.168.1.104:8887');
		//curl_setopt ($ch, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);

		curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile);
		curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile);

		curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

		if ($postdata){
			curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
			curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
		    'Content-Type: application/json',                                                                                
		    'Content-Length: ' . strlen($postdata))                                                                       
		);  
		}

		$html = curl_exec($ch);
		curl_close($ch);
		return $html;

	}
	file_put_contents('tmp/cookies.txt', '');

	$login = "[e-mail]";
	$pass = "dreesunderdress";

	$html = clrequest('https://www.target.com/');
	$html = clrequest('https://www.target.com/gsp/authentications/v1/credential_validations?client_id=ecom-web-1.0.0', '{"username":"'.$login.'","password":"'.$pass.'"}');
	print($html);
?>

Ответ на этот код :

{
  "errorCode": "T83072242",
  "errorKey": "_ERR_AUTH_DENIED",
  "errorMessage": "Please correct the following: Error Code T83072242. Your request was not completed. If you need help, you can call us at 800-316-3111.",
  "errorParameters": ""
}

А должен

{
	"errors": [{
		"errorKey": "_ERR_USER_DOES_NOT_EXIST",
		"errorMessage": "Sorry, either your e-mail or password didn't match what we have on file. Try it again?",
		"reason": "_ERR_USER_DOES_NOT_EXIST",
		"clientId": "ecom-web-1.0.0"
	}]
}
