Coinbase Invalid 404 request OAuth2 Guzzle - php

Question

I try make authorization in coinbase with OAuth2:
$client = new Client(['cookies' => true]);
try {
$response = $client->request('POST', $this->urlAccessToken, [
'headers' => [
'cache-control' => 'no-cache',
'Content-Type' => 'application/x-www-form-urlencoded'
],
'form_params' => [
'grant_type' => 'authorization_code',
'code' => $request->code,
'client_id' => $this->clientId,
'client_secret' => $this->clientSecret,
'redirect_uri' => $this->redirectUri
]
]);
dd($response->getBody());
} catch (\Exception $e) {
return response($e->getMessage(), 400);
}
After authorization in coinbase him me redirect to redirect URI and when send request exchange code i see bad response:
Client error: POST http://www.coinbase.com/oauth/token resulted in a 404 Not Found response: Invalid request. Instead of a GET request, you should be making a POST with valid POST params. For more informat (truncated...)
All code which will authorize in Coinbase:
private $clientId;
private $clientSecret;
private $redirectUri;
private $urlAuthorize;
private $urlAccessToken;
public function __construct()
{
$this->clientId = env('COINBASE_CLIENT_ID');
$this->clientSecret = env('COINBASE_CLIENT_SECRET');
$this->redirectUri = route('oauth2-redirect');
$this->urlAuthorize = 'https://www.coinbase.com/oauth/authorize';
$this->urlAccessToken = 'http://www.coinbase.com/oauth/token';
}
public function oauth(Request $request)
{
$state = hash('sha256', $request->session()->getId());
if (!isset($request->code)) {
$parameters = [
'response_type' => 'code',
'client_id' => $this->clientId,
'redirect_uri' => $this->redirectUri,
'state' => $state
];
$authorizationUrl = $this->urlAuthorize . '?' . http_build_query($parameters);
// Redirect the user to the authorization URL.
header('Location: ' . $authorizationUrl);
exit;
} elseif (empty($request->state) || $request->state !== $state) {
return response('Invalid state', 400);
} else {
$client = new Client(['cookies' => true]);
try {
$response = $client->request('POST', $this->urlAccessToken, [
'headers' => [
'cache-control' => 'no-cache',
'Content-Type' => 'application/x-www-form-urlencoded'
],
'form_params' => [
'grant_type' => 'authorization_code',
'code' => $request->code,
'client_id' => $this->clientId,
'client_secret' => $this->clientSecret,
'redirect_uri' => $this->redirectUri
]
]);
dd($response->getBody());
} catch (\Exception $e) {
return response($e->getMessage(), 400);
}
}
}

Problem was in URL access token, need use https://api.coinbase.com/oauth/token instead http://www.coinbase.com/oauth/token.
