  "pay_date": "2020-01-07 01:31:17",		//Payment Date

}

B. User Has Made Incorrect Payment (wrong amount) -

We use amount value of cryptocoins in the payment box with a small fraction after the decimal point to uniquely identify each of your users individually. If user pay wrong amount on your internal wallet address, OWC Gateway cannot identify that user. You need to process all unrecognised payments manually. We forward you ALL coins received on your internal wallet address/es including all payments with incorrect amounts (unrecognized payments).

In example below, user paid wrong/incorrect amount in 2.10 OWC to you -

{

  "status": "payment_unrecognized",	          //payment_unrecognized

  "confirmed": '0'                               //0 - unconfirmed payment or 1 - confirmed payment with 6+ confirmations

  "verify_hash": "",		 //Your transaction verify hash

  "orderid": "4",				//identifier for every order

  "userid": "32783",				//identifier for every user

  "amount": "2.30000000",			//Order amount(real amount to pay 2.30)(you have to pay this)

  "received_amount": "2.10000000",		//recieved amount(Payed amount 2.10) // not valid

  "addr": "RV6QC8mw7***E8HdXqqsnWybK",		//your internal wallet address which  you pay for it

  "txHash": "9722494a9ff3b5a578a1cb***",	//Your transaction hash

  "requestdate": "2020-01-07 01:33:18"		//Order request date

  "pay_date": "2020-01-07 01:34:24",		//Payment Date

}

We want response from your site on hit your callback url

You have to print response to your callback url on hit on it. Your response would be like this -

{
    "status":false,
    "hash":"Your secure key"     //md5(CONCAT(publicKey,privateKey,OrderId));
}

These function is only for PHP -

public function callback_function()
{
    $status=false;  //status for check response is valid or not
    $key='';
    if(isset($_POST['status'])){ //it's identify that status and other data set or not

        // Compare your OrderId and UserId with your order table (OrderId=$_POST['orderid'] and UserId=$_POST['userid'])
        if (Comparation is TRUE) {
            $key = md5(CONCAT(publicKey,privateKey,OrderId));
            $status = true;

            >> here update your data which have order OrderId=$_POST['orderid'] and UserId=$_POST['userid']
        }
    }
    echo json_encode(['status'=>$status,'hash'=>$key]);  // print the hash and status for verify that it's you
}
