Question

Attempting to make an authentication call to the API and keep getting

http code 400 w/ error message

error: unsupported_grant_type

error_description: grant type not supported

I'm making the call with php code below

$server = curl_init($this->api_token_url);

curl_setopt($server, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));

curl_setopt($server, CURLOPT_POST, 1);

$parms = array('grant_type' => 'password',

'client_id' => $this->client_id,

'client_secret' => $this->api_key,

'username' => $this->username,

'password' => $this->password . $this->security_token);

curl_setopt($server, CURLOPT_POSTFIELDS, $parms);

curl_setopt($server, CURLOPT_RETURNTRANSFER, 1);

$data = json_decode(curl_exec($server), true);

Thanks for the help!
