Create ZOHo DESK webhook API

Create ZOHo DESK webhook API

Hi,

I a working with ZOHO DESK API, which is working fine.

Now I am testing ZOHO WEBHOOK API.

To check webhook API I need to first create ZOHO webhook . I just want to receive contact details to my web app when any contact is created in ZOHO DESK

When I run below PHP script to create ZOHO webhook API I am getting response (400) "bad request".

<?php
    
    $auth_token = '0e6934d204403eeaa67289xxxxxxxxxx'; //my_auth_token
    $org_id=6xxxxxxxx; //my_organization_id
    
    $ticket_data=array(
        "Contact_Add"=> null,
        );
    $headers=array(
            "Authorization: $auth_token",
            "orgId: $org_id",
            "contentType: application/json; charset=utf-8",
    );
    
    
    $ch= curl_init($url);
    curl_setopt($ch,CURLOPT_HTTPHEADER,$headers);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);
    curl_setopt($ch,CURLOPT_POST,TRUE);
     curl_setopt($ch, CURLOPT_POSTFIELDS,$ticket_data);
     
    $response= curl_exec($ch);
    $info= curl_getinfo($ch);
    
    if($info['http_code']==200){
        echo "<h2>Request Successful, Response:</h2> <br>";
        echo $response;
       
    }
    else{
        echo "Request not successful. Response code : ".$info['http_code']." <br>";
        echo "Response : $response";
    }
    
    curl_close($ch);
    
?>
