How to get response on url specified in UPI Hyperlink payment

Question

I'm trying to pay through a UPI hyperlink like

upi://pay?pa=abc@upi&pn=payeeName&tr=1234&tn=Pay%20to%20payeeName&am=1&mam=1&cu=INR&url=https://test.com/payment/orderId=123456

• I am sending above link through sms
• When I click on link it shows UPI application list as option
• I have selected BHIM app (also tried other applications)
• Then completed payment, till now it works fine.

After the UPI payment is done, the Spring controller which handles the "callback" request to https://test.com/payment/orderId=12345, is not getting called.

So how to get response of UPI Hyperlink payment in Java correctly?

Edit:

This is the controller method. I have also tried @GetMapping instead of @PostMapping.

@PostMapping("/payment")
public ModelAndView credPayment(HttpServletRequest request) {

    String key = request.getParameter("orderId");
    String txnId = request.getParameter("txnId");
    String responseCode = request.getParameter("responseCode");
    String approvalRefNo = request.getParameter("ApprovalRefNo");
    String status = request.getParameter("Status");
    String txnRef = request.getParameter("txnRef");
    System.out.println("Parameter Names");
    while (request.getParameterNames().hasMoreElements()) {
        System.out.println(request.getParameterNames().nextElement());
    }

    System.out.println("Header Names");
    while (request.getHeaderNames().hasMoreElements()) {
        System.out.println(request.getHeaderNames().nextElement());
    }

    System.out.println("txnId : "+txnId);
    System.out.println("responseCode : "+responseCode);
    System.out.println("ApprovalRefNo : "+approvalRefNo);
    System.out.println("Status : "+status);
    System.out.println("txnRef : "+txnRef);

    ModelAndView modelAndView = new ModelAndView();
    modelAndView.setViewName("redirect:/");
    return modelAndView;
}

Answer 1

The URL parameter in the payment link is not a callback URL. And currently no payment app is using it for that purpose.

The URL is only meant to provide transaction information to the payer.

Answer 2

If I understood it correctly, your redirect URL is

https://test.com/payment/orderId=123456

And when this is called, you need to get order id value in your controller.

Then try changing your method to something like this:

@GetMapping(value = "/payment/{order}")
public ModelAndView credPayment(@PathVariable("order") String order, HttpServletRequest request) {
    System.out.println(order); // prints orderId=123456
    ModelAndView modelAndView = new ModelAndView();
    modelAndView.setViewName("redirect:/");
    return modelAndView;
}

Issue:

You have configured your URL mapping as /payment only, so anything after that will get excluded from this mapping, eg: /payment/sdfdsfs

Uri myAction = Uri.parse("upi://pay?pa=******@****&pn="+"*******"+"&mc="+"&tid="+transaction_ref_id +"&tr="
                +transaction_ref_id +"&tn=Pay%20to%20*****%20*****%20App&am="+"1.00"+"&mam=null&cu=INR&url=https://mystar.com/orderid="+sOrderId);

        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_VIEW);
        intent.setData(myAction);
        startActivityForResult(intent, 100);

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 100) {
            if (resultCode == RESULT_OK) {
                String res = data.getStringExtra("response");
                if (res.contains("Status=SUCCESS")) {
                    Toast.makeText(context, "Payment successful!", Toast.LENGTH_LONG).show();
                }
                else {
                    Toast.makeText(context, "Payment was not successful! Try again later", Toast.LENGTH_LONG).show();
                }
            }
            else {
                Toast.makeText(context, "Payment was not successful!", Toast.LENGTH_LONG).show();
            }
        }
    }

Your problem is with you method signature. Try to add the response to your method parameter so you can get the response object. Change your method to:

public ModelAndView credPayment(HttpServletRequest request, HttpServletResponse response)
