Guzzle vs CURL for interacting with vtiger web services, CURL works but Guzzle does not

Question

I am implementing a client to consume vtiger REST API and in the login process I manage to get it working with curl but not with Guzzle.

Guzzle code:

$postData = [
    'operation' => 'login',
    'username' => $userName,
    'accessKey' => $generatedKey
];

$response = $client->post($url, [
    'form_params' => $postData
]);

There is not actual Guzzle error or exception but is just that I am not being able to authenticate:

{"success":false,"error":{"code":"INVALID_AUTH_TOKEN","message":"Specified token is invalid or expired"}}

Curl version:

$curl = curl_init($service_url);
$curl_post_data = array(
    'operation' => 'login',
    'username' => $crm_username,
    'accessKey' => md5($crm_token.$crm_useraccesskey),
);

curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);

I prefer to use Guzzle but right now I have no clue why it dos not work in Guzzle but it does using curl. Any ideas?

Please, provide more information about the resulting error. What error do you get with Guzzle version from the server? — Alexey Shokov, Aug 25 '16 at 14:37
@AlexeyShockov there is not actual Guzzle error but just I am not getting the expected response despite sending the correct data — DanielRestrepo, Aug 26 '16 at 13:21

 $response = $client->request('POST','',['form_params' => ['operation'=>'getchallenge', 'username'=>$userName]  ] )

The above won't work, but return crm_token and

$response = $client->request('GET','',['query' => ['operation'=>'getchallenge', 'username'=>$userName] ] )

works fine.

Is $generatedKey in the first code is the same as md5($crm_token.$crm_useraccesskey) in the second code ? if No, then correct it and it probably works. If not, based on documentation for Guzzle 6.0, for post requests , you can do as following:

$postData = [
    'operation' => 'login',
    'username' => $userName,
    'accessKey' => $generatedKey
];

$response = $client->request('POST',$url, [
    'form_params' => $postData
]);

for more information, see this: http://docs.guzzlephp.org/en/latest/request-options.html#form-params

Really late to the party but hopefully this will help someone else who has the same problem.

This works fine for me using Guzzle 6.0

use GuzzleHttp\Client;

// vTiger API constants
define('VT_URL', 'http://yoursite.com/webservice.php');
define('VT_USERNAME', 'the_name_of_the_user');
define('VT_ACCESSKEY', 'your_accesskey');

$client = new Client(); //GuzzleHttp\Client

// perform API GET request
$reponse = $client->request('GET', VT_URL, [
    'query' => [
        'operation' => 'getchallenge',
        'username' => VT_USERNAME
    ]
]);

// decode the response
$challenge = json_decode($reponse->getBody());

// If challenge failed
if($reponse->getStatusCode() !== 200 || !$challenge->success) {
    die('getchallenge failed: ' . $challenge['error']['errorMessage']);
}

// Everything ok so create a token from response
$token = $challenge->result->token;

// Create unique key using combination of challengetoken and accesskey
$generatedkey = md5($token . VT_ACCESSKEY);

// login using username and accesskey
$reponse = $client->request('POST', VT_URL, [
    'form_params' => [
        'operation' => 'login', 
        'username' => VT_USERNAME, 
        'accessKey' => $generatedkey
    ]
]);

// decode the response
$login_result = json_decode($reponse->getBody()->getContents());

// If api login failed
if($reponse->getStatusCode() !== 200 || !$login_result->success) {
    die('login failed: ' . $login_success['error']['errorMsg']);
}

$sessionid =  $login_result->result->sessionName;

Then you can use the $sessionid to perform other queries
