user not redirecting after successful payment

[Waqas Saeed 0]

Hello!

I have a difficulty find out the reason. my code is mentioned below; the only problem am having is that the after payment is successful, the user is not redirected through php header; although have tried javascript redirect but unfortunately does not work after payment gateway send params to the callback file. however there is no problem in logs and payment. as mentioned above. 

code :: 

if ($status_api=="PAID"){


    addInvoicePayment(
        $invoiceId,
        $transactionId,
        $paymentAmount,
        0,
        $gatewayModuleName
    );

	logTransaction($gatewayParams['name'], $response, "PAID");
	header('Location: '.$systemUrl.'viewinvoice.php?id='.$invoiceId.'&paymentsuccess=1');
 }

Try putting the following under the header line:

exit();

Unfortunately that wasn't the issue due to the header, or window.location.replace,

the gateway response to the callback file consist of 2 similar responses (HTTP response after successful payment, and Click Button with GET variables) that was actually duplicating the transaction_id, log transaction does not work for duplicated transaction id and freezes,  I've added a localAPI that checks the invoice is Paid that does not execute AddPayment and redirects to the invoice page.
