Response API asynchronous notification

Masters, I need your help for my API Integration.

This is details step by step of my Web App :
- I will sending all of parameters (like amount billing, code bank, username, email etc) for payment to the API
This is the sample request : 
$params = [              
  'merchantCode' => $merchantCode,              
  'orderType' => $orderType,              
  'orderNum' => $orderNum,              
  'pay' => $pay,              
  'name' => $name,              
  'email' => $email,              
  'phone' => $phone,              
  'notif' => $notifyUrl,              
  'date' => $dateTime,              
  'expired' => $expiryPeriod,              
  'sign' => $sign        
];

- API will sending asynchronous response with detail is it my request is Success or not.

This is the sample of response from API : 

RespCode :SUCCESS RespMessage :Request Transaction Success OrderNum :QWOIJDDJ orderNum :2024061123981 payMoney :10000 platSign :HayKQWNzo2vlKcEZ

- After receiving asynchronous notification, I need to respond to SUCCES the string to check is it my customer already paid the billing or not.

This is the sample of code : 

$res = json_decode(file_get_contents('php://input'), true);$platSign = $res['platSign'];unset($res['platSign']);
Because I need to check my customers already paid the billing or not. So, My question is :
 
How to sending all of API response before, using json_decode(file_get_contents('php://input), true);
I'm so sorry if my English is bad, if you confused with my question please let me know.

What kind of response is expected by the payment system?

They expect is to sending response SUCCESS using 
$res = json_decode(file_get_contents('php://input'), true);
after that, create new variable and get value from 'platSign' parameters. 


Example :


$res = json_decode(file_get_contents('php://input'), true);
$platSign = $res['platSign'];
unset($res['platSign']); 

//Decrypt Sign

$decrypt = $this->Encrypt->public_key_decrypt($platSign, $myOwnPublicKey);

I don't know if this is what you're looking for but it might help. I'm only an amateur but I'm doing something similar with sage accounting and it looks like below. apihandler_perform sends a request to sage using oauthClient. The oauthClient response is then returned from apihandler_perform which is then sent back to whatever it was that called process_invoice(). In my case the 2fa token expires after 3 minutes so before my api handler sends data to sage, it checks if the token is valid and renews it if not and then sends the data.

PHP Code:
public function process_invoice(){
        try {
            
$data json_decode(file_get_contents('php://input'));
            
$sage_id=$this->apihandler_perform('invoices','get',$data);
            
$this->sendResponse(['sage_id'=>$sage_id]);
        } catch (
Exception $e){
            
$this->sendResponse(['error'=>$e->getMessage()]);
        }
    }
    public function 
sendResponse($result$httpcode 200): void
    
{
        
$result json_encode($result);
        
header('HTTP/1.1: '.$httpcode);
        
header('Status: '.$httpcode);
        
header('Content-Length: ' strlen($result));
        
header('Content-type: ' 'application/json');
        echo 
$result;
    }

This is the sample code that they are using.
