Push Notifications Console: Apple’s Recreation-Altering New Device


At WWDC ’23, Apple introduced the Push Notifications Console, a much-needed new device to simplify creating and testing your push notifications.

For years, builders have struggled with push notifications. Every developer needed to write customized scripts to not solely generate the suitable payload, but in addition deal with the authentication to APNs. In later years, Apple simplified the method by permitting the simulator to set off a notification by dropping in a JSON payload.

Due to the Push Notifications Console, now you can say goodbye to these clunky, outdated strategies. However first, you’ll check out how push notifications have labored thus far.

Observe: If you might want to brush up in your push notification abilities, try our guide: Push Notifications by Tutorials. It covers every part you might want to learn about wealthy media notifications, notification actions, grouped notifications and extra.

Sending Push Notifications — the Outdated Approach

Till now, while you wanted push notifications, you’ve in all probability written a script with code like this:


perform generateAuthenticationHeader()
{
  $header = base64_encode(json_encode(['alg' => 'ES256', 'kid' => AUTH_KEY_ID]));
  $claims = base64_encode(json_encode(['iss' => TEAM_ID, 'iat' => time()]));

  $pkey = openssl_pkey_get_private('file://' . AUTH_KEY_PATH);
  openssl_sign("$header.$claims", $signature, $pkey, 'sha256');

  $signed = base64_encode($signature);

  return "$header.$claims.$signed";
}

perform sendNotifications($token, $debug) {
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_2_0);
  curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($GLOBALS['payload']));
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_HTTPHEADER, [
      'apns-topic: ' . BUNDLE_ID,
      'authorization: bearer ' . generateAuthenticationHeader(),
      'apns-push-type: alert'
  ]);

  $server = $debug ? 'api.improvement' : 'api';
  $url = "https://$server.push.apple.com/3/machine/$token";
  curl_setopt($ch, CURLOPT_URL, "{$url}");

  $response = curl_exec($ch);
  if ($response === false) {
    echo("curl_exec failed: " . curl_error($ch));
    proceed;
  }

  $code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  if ($code === 400 || $code === 410) {
    $json = @json_decode($response);
    if ($json->purpose === 'BadDeviceToken') {
        // Do one thing right here.
    }
  }

  curl_close($ch);
}

Whereas that works, it isn’t fairly.

Varied apps from the Mac App Retailer additionally promise to make push notifications simpler, however they ceaselessly don’t sustain with adjustments to the APN’s packet format and headers you could want to use.

Now, you’ll check out the Push Notifications Console and the way it improves push notification testing.
