Hi,

I am trying to send a push notification via PHP-curl and command-line curl for http2 but after trying possible methods I end up getting the same error response "curl: (55) Failed sending HTTP POST request"

Curl

Code Block curl -v -d '{"aps":{"alert":"Hello"},"yourCustomKey":"11"}' \-H "Content-Type: application/json" -X POST \
--http2 https://api.development.push.apple.com/3/device/DEVICE_TOKEN \
-H ':method: POST' \
-H ':scheme: https' \
-H ':path: /3/device/DEVICE_TOKEN' \
-H 'authorization: bearer TOKEN' \
-H 'apns-id: b150795-35ea-4894-a289-85e343936cca' \
-H 'apns-push-type: alert' \
-H 'apns-expiration: 1609919807' \
-H 'apns-priority: 10' \
-H 'apns-topic: com.company.suffix' \
-H 'apns-collapse-id: 9cb3190c-6046-4b7c-8cf4-61c6d05fd724'

Output:

What is wrong with my CURL request?
Any hit would be helpful, thanks.

You don't seem to have a payload to send. Your curl command is missing the "--data" section.
Also, the URL you are using is an old one.

You may want to consult this article about sending push notifications using curl: https://developer.apple.com/documentation/usernotifications/sending_push_notifications_using_command-line_tools

Thanks for the reply, looks like I didn't post the full curl command, I am posting data as well, again I am getting the same error when using command line curl or PHP code.

Code Block curl -v --data '{"aps":{"alert":"Hello"},"yourCustomKey":"11"}' \
-H "Content-Type: application/json" -X POST \
--http2 https://api.push.apple.com/3/device/DEVICE_TOKEN \
-H ':method: POST' \
-H ':scheme: https' \
-H ':path: /3/device/DEVICE_TOKEN' \
-H 'authorization: bearer TOKEN' \
-H 'apns-id: b150795-35ea-4894-a289-85e343936cca' \
-H 'apns-push-type: alert' -H 'apns-expiration: 1609919807' \
-H 'apns-priority: 10' -H 'apns-topic: com.company.suffix' \
-H 'apns-collapse-id: 9cb3190c-6046-4b7c-8cf4-61c6d05fd724'

Code Block $url = "https://api.push.apple.com";
$headers = [
   ":method"=> 'POST',
    ":scheme" => "https",
   ":path"=> '/3/device/'.$devicetoken,
   "host" => "api.push.apple.com",
   "authorization" => 'bearer '.$bearerToken,
   "apns-id" => Str::uuid()->toString(),
   "apns-push-type"=> 'alert',
   "apns-expiration" => Carbon::now()->addMinutes(15)->getTimestamp(),
   "apns-priority" => 10,
   "apns-topic" => 'com.company.suffix',
   "apns-collapse-id" => Str::uuid()->toString()
];
foreach($headers as $header=>$value){
    $flatHeaders [] = $header.": ".$value;
}
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_PORT, 443);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $sample_alert);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_2_0);
curl_setopt($ch, CURLOPT_HTTPHEADER, $flatHeaders);
$response = curl_exec($ch);
$httpcode = curl_getinfo($ch);
if ($response === FALSE) {
    return [
        'error' => curl_error($ch),
        'response' => $response,
        'httpcode' => $httpcode
    ];
    // throw new \Exception("Curl failed: " .  curl_error($ch));
}
