Not able to verify signature of payment

I have tried following code for verifying payment signature. But signature from payment and generated at my point are diffrent. Please let me know if i am doing something wrong here. Additionally in docs, there’s no sample code for nodejs. It will be really good if we can just find it there.

let generatedSignature = crypto
  .createHmac(
     "SHA256",
     "my-secret"
).update(payment.razorpay_payment_id + '|' + payment.razorpay_order_id)
.digest('hex');
let isSignatureValid = generatedSignature == payment.razorpay_signature;

Closing this issue, As I have figured out that the payment signature is generated using live mode secret key even though you are in test mode and the order was generated in test mode.

So if you want to check the Payment signature always use Live mode secret key. Above code will work if you use Live mode secret key.

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: "[e-mail]",
    contact: "[phone]",
  },
};
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();

};
