Order is an important step in the payment process.
- An order should be created for every payment.
- You can create an order using the . It is a server-side API call. Know how to Orders API.
- The

received in the response should be passed to the checkout. This ties the Order with the payment and secures the request from being tampered.
Handy Tips
You can capture payments automatically with the
on the Razorpay Dashboard.Create a file, for example, main.py
and add the API code given below:
import razorpayclient = razorpay.Client(auth=("YOUR_ID", "YOUR_SECRET"))data = { "amount": 500, "currency": "INR", "receipt": "order_rcptid_11" }payment = client.order.create(data=data)
Here is the list of parameters for creating an order:
amount
mandatory
integer
Payment amount in the smallest currency sub-unit. For example, if the amount to be charged is ₹299.00, then pass 29900
in this field. In the case of three decimal currencies, such as KWD, BHD and OMR, to accept a payment of 295.991, pass the value as 295990. And in the case of zero decimal currencies such as JPY, to accept a payment of 295, pass the value as 295.
Watch Out!
As per payment guidelines, you should pass the last decimal number as 0 for three decimal currency payments. For example, if you want to charge a customer 99.991 KD for a transaction, you should pass the value for the amount parameter as 99990
and not 99991
.

Handy Tips
The open method of Razorpay object (rzp1.open()
) must be invoked by your site's JavaScript, which may or may not be a user-driven action such as a click.
The way the Payment Success and Failure scenarios are handled depends on the
you used in the last step.If you used the sample code with the callback URL:
Razorpay makes a POST call to the callback URL with the razorpay_payment_id, razorpay_order_id and razorpay_signature in the response object of the successful payment. Only successful authorisations are auto-submitted.
If you used the sample code with the handler function:
The customer sees your website page. The checkout returns the response object of the successful payment (razorpay_payment_id, razorpay_order_id and razorpay_signature). Collect these and send them to your server.
Use the Success/Failure Handling code given below:
"handler": function (response){alert(response.razorpay_payment_id);alert(response.razorpay_order_id);alert(response.razorpay_signature)}
Multiple payment methods are available on Razorpay Standard Checkout.
- The payment methods are fixed and cannot be changed.
- You can configure the order or make certain payment methods prominent. Know more about configuring payment methods. Know more about .
A successful payment returns the following fields to the Checkout form.
- You need to store these fields in your server.
- You can confirm the authenticity of these details by verifying the signature in the next step.
razorpay_payment_id
string
Unique identifier for the payment returned by Checkout only for successful payments.
razorpay_order_id
string
Unique identifier for the order returned by Checkout.
razorpay_signature
string
Signature returned by the Checkout. This is used to verify the payment.
This is a mandatory step that allows you to confirm the authenticity of the details returned to the checkout for successful payments.
To verify the razorpay_signature
returned to you by the checkout:
-
Create a signature in your server using the following attributes:
-
Use the SHA256 algorithm, the
razorpay_payment_id
and theorder_id
to construct a HMAC hex digest as shown below:generated_signature = hmac_sha256(order_id + "|" + razorpay_payment_id, secret);if (generated_signature == razorpay_signature) {payment is successful} -
If the signature you generate on your server matches the
razorpay_signature
returned to you by the checkout, the payment received is from an authentic source.Use the code given below to generate signature on your server:
