Trustpilot Oauth use token PHP - php

Question

I retrieve the Oauth token in Trustpilot with this script
function get_accesstoken($tp_username,$tp_password,$api_key,$api_secret)
{
$url = 'https://api.trustpilot.com/v1/oauth/oauth-business-users-for-applications/accesstoken';
$payloadName = array(
'grant_type' => 'password',
'username' => $tp_username,
'password' => $tp_password
);
$payload = http_build_query($payloadName);
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($curl, CURLOPT_USERPWD, "$api_key:$api_secret");
curl_setopt($curl, CURLOPT_TIMEOUT, 30);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $payload);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
$return = json_decode(curl_exec($curl));
print_r($return);
curl_close($curl);
return $return->access_token;
}
now, how can I retrieve the token, verify is exist and use it?
thanks

$url = "https://api.trustpilot.com/v1/oauth/oauth-business-users-for-applications/accesstoken";
$key = "YOUR API KEY";
$secret = "YOUR API SECRET";
$username = 'YOUR LOGIN EMAIL';
$password = 'YOUR LOGIN PASSWORD';
$payload = array(
'grant_type' => 'password',
'username' => $username,
'password' => $password,
);
$authEncodedKeys = base64_encode($key.":".$secret);
$options = array(
'http' => array (
'header' => "Authorization: Basic ".$authEncodedKeys.
"Content-Type: application/x-www-form-urlencoded",
'method' => 'POST',
'content' => http_build_query($payload)
)
);
$context = stream_context_create($options);
$results = json_encode(file_get_contents($url, false, $context));
echo $results;
This works for me. Try it.
