Test Mode - Verification of Razorpay Signature Failed

[SHAHRUKH-KHAN]

Hi Team,

This is related to the closed issue.

router.post("/verifypayment", function(req, res) {
    var paymentsignature = req.body;

    console.log(paymentsignature);

    var generated_signature = crypto.createHmac('sha256','my-secret')
        .update(paymentsignature.order_id + '|' + paymentsignature.razorpay_payment_id)
        .digest('hex');
    if (generated_signature == paymentsignature.razorpay_signature) {    
        console.log('matched'); 
    } else {
        console.log('not matched');
    }
});

The signature is generated which is not matched. variables used above:

1. order_id - custom-generated (not the one returned from Razorpay)
2. razorpay_payment_id - Returned by Razorpay Checkout.

+1 if you face the same. Razorpay Team - Please look into this.

Can you try this once, to generate signature

expected_signature = razorpay_invoice_id + '|' +
                     razorpay_invoice_receipt + '|' +
                     razorpay_invoice_status + '|' +
                     razorpay_payment_id;

@umanghome Can we expect an update on this?

I am getting undefined values of razorpayOrderId and razorpaySignature from the handler response while working on test mode. So the payment verification fails in the backend. I have been stuck at this for over a day now. Any help is highly appreciated.

This is my code snippet:

` const launchRazorpay = async () => { const order = await axios.post"http://localhost:8081/api/subscription/pay");

const { amount, id: order_id, currency } = order.data;

console.log(order);

const options = {
  key: "rzp_test_asdfg345dfCVBN",
  amount: amount,
  currency: currency,
  name: "Razorpay",
  description: "PAY YOUR SUBSCRIPTION FEES",
  image: `${process.env.PUBLIC_URL}/assets/images/logo.png`,
  orderId: order_id,
  handler: function (response) {
    alert(response.razorpay_payment_id);// pay_asd1234
    alert(response.razorpay_order_id);// undefined
    alert(response.razorpay_signature);// undefined
  },
  prefill: {
    name: "abc",
    email: "abc@gmail.com",
    contact: "+911234567890",
  },
};
console.log("====================================");
console.log(options.orderId === order_id); // true
console.log(response.razorpay_order_id === order_id);// false
console.log("====================================");
const paymentObject = new window.Razorpay(options);
paymentObject.open();

};

`

@DibyajyotiMishra were you able to fix this.I am facing the same issue in live mode but works fine in test

[DibyajyotiMishra]

yes. The function should be async.

handler: async function (response) {
        const data = {
          orderId: order_id,
          doneBy: authState.userId,
          institutionType: authState.userType,
          razorpayPaymentId: response.razorpay_payment_id,
          razorpayOrderId: response.razorpay_order_id,
          razorpaySignature: response.razorpay_signature,
        };

console.log(data);

Hope it helps.

@SHAHRUKH-KHAN @DibyajyotiMishra Sorry for the delay . the sdk is updated now for payment signature you can use this code snippet var { validatePaymentVerification } = require('razorpay/dist/utils/razorpay-utils');

const respBody = { 'subscription_id':'sub_ID6MOhgkcoHj9I', 'payment_id':'pay_IDZNwZZFtnjyym' } const correctSignature = '601f383334975c714c91a7d97dd723eb56520318355863dcf3821c0d07a17693' secret = 'EnLs21M47BllR3X8PSFtjtbd'; validatePaymentVerification(respBody, correctSignature, secret)

you can also use this doc
