Using discord API with PHP & cURL

Question

i've made a bot on discord, and i want to make request to the API to manage channels, display messages, those kind of things. I've started by using Postman, to make some calls to the API, it works fine.

Link to the API : https://discordapp.com/developers/docs/intro

Then i tried to do the request using PHP(wamp), with cURL, the request is sent, but the API send me back a 401 Unauthorized response, despite the fact that I sent the correct Authorization header. I've added the verbose option to get more infos :

* Hostname in DNS cache was stale, zapped

*   Trying 104.16.58.5...

* Connected to discordapp.com (104.16.58.5) port 443 (#0)

My code :

$url = 'https://discordapp.com/api/channels/230833430827499520/messages';

$ch = curl_init();
$f = fopen('request.txt', 'w');
curl_setopt_array($ch, array(
    CURLOPT_URL            => $url, 
    CURLOPT_HTTPHEADER     => array('Authorization : Bot <TOKEN>'), 
    CURLOPT_RETURNTRANSFER => 1,
    CURLOPT_FOLLOWLOCATION => 1,
    CURLOPT_VERBOSE        => 1,
    CURLOPT_SSL_VERIFYPEER => 0,
    CURLOPT_STDERR         => $f,
));
$response = curl_exec($ch);
fclose($f);
curl_close($ch);

I tried file_get_contents as well but didn't work. I can't see what's wrong, maybe SSL certificate? Any thoughts?

Solution

Ok, i just had to remove the first space in the header

CURLOPT_HTTPHEADER     => array('Authorization: Bot <TOKEN>')

instead of

CURLOPT_HTTPHEADER     => array('Authorization : Bot <TOKEN>'),
