Answer 1

This URL https://api.parse.com/1/events/AppOpened
return {} or true means your app lauched. You can check responsecode by
$responseCode = curl_getinfo($rest, CURLINFO_HTTP_CODE);
echo "<pre>";
print_r($responseCode);
echo "</pre>";
I have checked with other url https://api.parse.com/1/classes/Player, as it's working fine. check following code:
$headers = array(
"X-Parse-Application-Id:trPYPHrI1Cfb8Q4w3TQ5HY7RoDcOFSM4okdNWDyC" ,
"X-Parse-REST-API-Key:OeNTANdx5A6ILHIZi3NfVcuE3GPDg4Cmyo9aQM1R",
"Content-Type: application/json"
);
$data='{ }';
$rest = curl_init();
curl_setopt($rest,CURLOPT_URL,"https://api.parse.com/1/classes/Player");
curl_setopt($rest,CURLOPT_HTTPHEADER,$headers);
curl_setopt($rest, CURLOPT_POST,true);
curl_setopt($rest, CURLOPT_RETURNTRANSFER, true);
curl_setopt($rest, CURLOPT_POSTFIELDS, $data);
$response = curl_exec($rest);
echo "<pre>";
print_r($response);
echo "</pre>";
curl_close($rest);
