How to update a field via API?

👨‍💻 Development Help

I want to update a field in the Accounts module through API. But the problem is that When I update a field it updates successfully and it deletes the rest of the fields.

Which API are you using (v4.1 or v8)? And can you copy+paste your request here? But usually, you just provide those attributes that you want to set.

<?php
$url = "http://*instanceLink*/service/v4_1/rest.php";


function restRequest($method, $arguments){
 global $url;
 $curl = curl_init($url);
 curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
 
 
 $post = array(
         "method" => $method,
         "input_type" => "JSON",
         "response_type" => "JSON",
         "rest_data" => json_encode($arguments),
 );

//print_r($post); die;
 curl_setopt($curl, CURLOPT_POSTFIELDS, $post);
 
 $result = curl_exec($curl);
//   print_r($result);
 return json_decode($result,1);
}


$userAuth = array(
        'user_name' => 'username',
        'password' => md5('password'),
);
$appName = 'suiteCrm';
$nameValueList = array("name"=>"hello","value"=>"test");


$args = array(
            'user_auth' => $userAuth,
            'application_name' => $appName,
            'name_value_list' => $nameValueList);

$result = restRequest('login',$args);

$sessId = $result['id'];

$entryArgs = array(
    'session' => $sessId,
    'module_name' => 'Leads',
    "name_value_list"=>array(array(
        "id"=>$_POST['id'],
        "first_name"=>$_POST['first_name'],
        )
    )
    );
 $result = restRequest('set_entry',$entryArgs);

print_r($result);

I want to update only the name field in the Leads module. It will successfully update first_name. But other fields will be erased.
