[cesarecerpi]

Hello we have a connection problem with the server. We use this official class code in php to connect but it returns the error attached. You can help us ? Thanks in advance. Best regards

$sumup = new \SumUp\SumUp([
'app_id' => 'cc_classic_0JgS[edited]',
'app_secret' => 'cc_sk_classic_h3tRjaoz[edited]',
'grant_type' => 'client_credentials',
'scopes' => ['user.profile', 'transactions.history', 'user.app-settings', 'user.profile_readonly']
]);
$accessToken = $sumup->getAccessToken();
$merchantService = $sumup->getTransactionService($accessToken);
dd($merchantService->getTransactionHistory());
