3DS 2 Migration Guide - Browser Flow Cards Integration

If you integrated with our S2S APIs before October 15, 2022, you must make the following changes to your integration to accept card payments with the 3DS 2 authentication protocol.

Watch Out!

You must have a PCI compliance certificate to get this feature enabled on your account.

Quick Summary of Integration Changes

Ensure you make the following changes in your Create a Payment API request. There is no change in the response.

Handy Tips

The payment request and response would remain the same for both frictionless and challenge scenarios.
The payment request would remain the same for redirection and native OTP flows.

Request Parameters

amount

mandatory

integer Payment amount in the smallest currency sub-unit. For example, if the amount to be charged is ₹299, then pass 29900 in this field.

currency

mandatory

string Currency code for the currency in which you want to accept the payment. For example, INR. Refer to the list of supported currencies. The length must be 3 characters.

cvv

string CVV printed on the back of the card.

Handy Tips

CVV is not required by default for tokenised cards across all networks.
CVV is optional for tokenised card payments. Do not pass dummy CVV values.
To implement this change, skip passing the cvv parameter entirely, or pass a null or empty value in the CVV field.
We recommend removing the CVV field from your checkout UI/UX for tokenised cards.
If CVV is still collected for tokenised cards and the customer enters a CVV, pass the entered CVV value to Razorpay.

redirect: This URL redirects the customer to submit the OTP on the bank page.

url

string URL to be used for the action indicated.

OTP Generation

If you would like the customer to enter the OTP on your website instead of the bank page, use the otp_generate URL. When this URL is triggered, you get the following response:

curl -u [YOUR_KEY_ID]
-X POST https://api.razorpay.com/v1/payments/pay_FVmAstJWfsD3SO/otp_generate
-H "Content-Type: application/json" \

Response Parameters

If the payment request is valid, the response contains the following fields.

array A list of action objects available to you to continue the payment process. Present when the payment requires further processing.

action

string An indication of the next step available for payment processing. Possible values:

opt_submit - Use this URL to allow the customer to submit OTP and complete the payment on your webpage.
opt_resend - Use this URL to resend OTP to the customer.

url

If the customer faces any latency issues, you can choose to cancel this request and redirect the customer to the bank page to enter the OTP and complete the payment. Thus, you can avoid payment failure by switching the customer to the bank page payment flow.

Response on Submitting OTP

Curlec sends the respective success or failure response after the customer submits the OTP on your page.

The following endpoint submits the OTP:

POST

payments/:id/otp/submit

After the payment is completed, the final response is posted to the URL given in callback_url of the request, and can then be verified.

Next Step

S2S JSON V2 Cards Build Integration document
