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 Curlec 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 an 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:
$api = new Api($key_id, $secret);$api->utility->verifyPaymentSignature(array('razorpay_order_id' => $razorpayOrderId, 'razorpay_payment_id' => $razorpayPaymentId, 'razorpay_signature' => $razorpaySignature));
Handy Tips
On the Dashboard, ensure that the payment status is captured
. Refer to the payment capture settings page to know how to
You can track the payment status in three ways:
To verify the payment status from the Dashboard:
- Log in to the and navigate to Transactions → Payments.
- Check if a Payment Id has been generated and note the status. In case of a successful payment, the status is marked as Captured.
After the integration is complete, a Pay button appears on your webpage/app.
Click the button and make a test transaction to ensure the integration is working as expected. You can start accepting actual payments from your customers once the test transaction is successful.
You can make test payments using one of the payment methods configured at the Checkout.
Watch Out!
This is a mock payment page that uses your test API keys, test card and payment details.
- Ensure you have entered only your in the Checkout code.
- No real money is deducted due to the usage of test API keys. This is a simulated transaction.
Following are all the payment modes that the customer can use to complete the payment on the Checkout.
Following are the payment methods supported as configured at Curlec Checkout.
You can select any of the listed banks. After choosing a bank, Curlec will redirect to a mock page where you can make the payment a success
or a failure
. Since this is Test Mode, we will not redirect you to the bank login portals.
You can select any of the listed wallets. After choosing a wallet, you will be redirected to a mock page where you can make the payment success
or a failure
. Since this is Test Mode, we will not redirect you to the wallet login portals.

iOS integration for Touch'n Go wallet is currently unavailable. We will be adding support for it soon.
You can use one of the following test cards to test transactions for your integration in Test Mode.
- Use any valid expiration date in the future in the MM/YY format.
- Use any random CVV to create a successful payment.

.Check the go-live checklist for Curlec Web Standard Checkout integration. Consider these steps before taking the integration live.
You can perform an end-to-end simulation of funds flow in the Test Mode. Once confident that the integration is working as expected, switch to the Live Mode and start accepting payments from customers.
Watch Out!
Ensure you are switching your test API keys with API keys generated in Live Mode.
To generate API Keys in Live Mode on your Curlec Dashboard:
- Log in to the and switch to Live Mode on the menu.
- Navigate to Account & Settings → API Keys → Generate Key to generate the API Key for Live Mode.
- Download the keys and save them securely.
- Replace the Test API Key with the Live Key in the Checkout code and start accepting actual payments.
After payment is authorized
, you need to capture it to settle the amount to your bank account as per the settlement schedule. Payments that are not captured are auto-refunded after a fixed time.
Watch Out
- You should deliver the products or services to your customers only after the payment is captured. Curlec automatically refunds all the uncaptured payments.
- You can track the payment status using our or webhooks.
- Auto-capture payments (recommended)
Authorized payments can be automatically captured. You can auto-capture all payments on the Curlec Dashboard.
