I'm trying to call a .NET api controller from php
  $user = $ctl->getUser();
        $client = $ctl->getCurrentClient();
        $userid = $user->getID();
        $clientid = $client->getID();
        $data = array('userid' => $userid, 'clientid' => $clientid);
        $data_string = json_encode($data);           
          $ch = curl_init('https://localhost:44346/api/participantapi/TransferParticipants');
          curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");             
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
            'Content-Type: application/json',
            'Content-Length: ' . strlen($data_string))                   
        );          
        $result = curl_exec($ch);
        print_r($result);
        curl_close($ch);
My controller looks like
    [HttpPost]
    [Route("TransferParticipants")]
    public IActionResult TransferParticipants(JObject data)
If I make the call from postman it works fine. But when I make this call from the php code, I don't see anything. Is there anyway for me to see what I'm missing. Any help would be much appreciated.
I tried the options from that post and still no luck. It seems like it isn't sending at all.
