Trying to get data from IOT using PHP - php

Question

I'm trying to get JSON from my IOT application. I can post data to my IOT application so my connection is ok but cant get a response. I only get a not allowed error.
I use this code:
$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, true);
$verbose = fopen('php://temp', 'w+');
curl_setopt($ch, CURLOPT_STDERR, $verbose);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$endpoint_url);
$result = curl_exec($ch);
if ($result === FALSE) {
printf("cUrl error (#%d): %s<br>\n", curl_errno($ch),
htmlspecialchars(curl_error($ch)));
}
curl_close($ch);
rewind($verbose);
$verboseLog = stream_get_contents($verbose);
echo "Verbose information:\n<pre>", htmlspecialchars($verboseLog), "</pre>\n";
But all I get back is the following:
Verbose information:
* Hostname integrations.thethingsnetwork.org was found in DNS cache
* Trying 13.69.184.129...
* Connected to integrations.thethingsnetwork.org (13.69.184.129) port 443

How can I get the data?

You are not specifying the Request type in your curl request which automatically defaults it to a GET one. Add the following to your code.
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
