Api working on curl and not on GuzzleHttp - php

Question

I'm trying to connect to the Talentlink Api. I'm able to do it on curl but I can't connect using GuzzleHttp. I'm using Guzzle through the m6web/guzzle-http-bundle on Symfony. My code is below. Does anybody have an idea?
CURL
$headers = [
'username: XXXXX',
'password: XXXXX'
];
$body = '{
"searchCriteriaSorting": {
"categoryListsSorting": "LABEL",
"customLovsSorting": "ORDER",
"standardLovsSorting": "ORDER"
}
}';
$tuCurl = curl_init();
curl_setopt($tuCurl, CURLOPT_URL, "https://api3.lumesse-talenthub.com/CareerPortal/REST/FoAdvert/advertisement-by-id?api_key=XXXXXX&lang=FR&postingTargetId=1");
curl_setopt($tuCurl, CURLOPT_VERBOSE, 1);
curl_setopt($tuCurl, CURLOPT_HEADER, 1);
curl_setopt($tuCurl, CURLINFO_HEADER_OUT, 1);
curl_setopt($tuCurl, CURLOPT_HTTPHEADER, $headers);
$head = curl_exec($tuCurl);
$httpCode = curl_getinfo($tuCurl, CURLINFO_HTTP_CODE);
curl_close($tuCurl);
GUZZLE
$headers = [
'username' => 'XXXXXX',
'password' => 'XXXXXX'
];
try {
$response = $client->request('GET',
'https://api3.lumesse-talenthub.com/CareerPortal/REST/FoAdvert/advertisement-by-id?api_key=XXXXX&lang=FR&postingTargetId=1',
array(
'debug' => true,
$headers
));
} catch (ClientException $e) {
die((string)$e->getResponse()->getBody()->getContents());
}
On Guzzle, I keep getting a page with a login form as if I wasn't connected. However, the status is always 200 so it's difficult to debug.
SOLUTION
It was a problem with the array I was sending. It should be like this wit the 'header' key:
$response = $client->request('GET',
'https://api3.lumesse-talenthub.com/CareerPortal/REST/FoAdvert/advertisement-by-id?api_key=XXXX&lang=FR&postingTargetId=1',
[
'headers' => $headers,
//'debug' => true
]);
