PHP Guzzle request not working. Works fine with CURL

Question

So i'm just getting started trying to understand Guzzle but one of my requests keeps returning an error, even though the exact same request when done using CURL works just fine. They look identical to me, but maybe i'm missing something about how Guzzle works. I've removed my access tokens and transaction ids for security reasons, obviously the real one I was using had the actual strings in properly. I am using the Freeagent API although I don't think which API i'm talking to has anything to do with it.

I'm sure it's a simple error stemming from me not understanding how Guzzle works, but to me this Guzzle request and Curl request look identical, so I don't understand why i'm getting an error with one and a successful request with the other.

The Guzzle request that results in an error:

$access_token = '{my_access_token_removed}';
$url = 'https://api.freeagent.com/v2/bank_transactions/{myid}';

$guzzleClient = new Client([
    'verify'    =>  false
]);

$request = $guzzleClient->get($url, array(
    'debug'     =>  true,
    'headers'   =>  array(
        'User-Agent' => 'sortitoutsi',
        'Accept' => 'application/json',
        'Content-Type' => 'application/json',
        'Authorization' => $access_token
    )
));

This CURL request works just fine:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Authorization: Bearer '.$access_token,
    'Accept: application/json',
    'Content-Type: application/json',
));
curl_setopt($ch, CURLOPT_USERAGENT, 'sortitoutsi');
curl_setopt($ch, CURLOPT_TIMEOUT, 3);

$json_response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

Any ideas? I've copy and pasted the entire debug info and stack trace below. I am also using Laravel, although again I can't see that being an issue.

I've not used Guzzle much, but I have Client class constructed with two parameters: a protocol+domain (api.freeagent.com) and an options array. The get() call only specifies the url without the domain. Your url is https, but the debugging says that an HTTP request was used. > GET /v2/bank_transactions/{id_removed} HTTP/1.1 — user2867342
I've tried it both with a base url and specifying the full url in the get with the same response and the $url definitely has https. — John Mellor
Calling without the https doesn't include the server certificate at the top, which implies to me it is using https — John Mellor

So I figured this out myself. It was simply a human typo, it should have been:

'Authorization: Bearer '.$access_token

instead of

'Authorization: '.$access_token

The freeagent api was actually telling me this in the response, but guzzle wasn't giving me the wrong.

To get the response I simply did:

try {
    $request = $this->guzzle->request('get', $url, array(
        'debug'     =>  true,
        'headers'   =>  array(
            'User-Agent' => 'sortitoutsi',
            'Accept' => 'application/json',
            'Content-Type' => 'application/json',
            'Authorization' => 'Bearer '.$access_token
        )
    ));
} catch (ClientException $e) {
    die((string)$e->getResponse()->getBody());
}

Then I could easily see my error based on the json response from the api
