Handling Guest Checkout Transactions

Guest Checkout is a valuable feature that can provided be enabled for your e-commerce websites. It allows your customers to make purchases without the need to sign in or create a user account. This streamlined process benefits one-time or occasional shoppers, as it eliminates the registration step, leading to faster transactions and enhanced customer satisfaction.

Enable this feature:

To enable this feature, contact your PayU Key Account Manager or PayU Integration Support.

As per RBI compliances, acquirers are also not allowed to store card details after a stipulated timeline. As per recommendations from RBI end, Guest checkout transactions won’t be allowed post 31st Oct. 2023. Guest checkout PAN should be replaced with some alternative number for transaction processing. As per the new regulations on guest checkout, where we have to tokenise plain card numbers. This token is called Alternative ID or Alt ID.

There are three scenarios with Alternative ID:

Scenario 1: Provision & processes guest transaction with PayU

No changes required in the _payment request used to collect payments.

Scenario 2: Provision Alt ID outside PayU and use PayU to Process Transaction

Request parameters

Along with the parameters listed in the Collect Payment API - Cards (Merchant Hosted Checkout), you have to pass alt ID as a variable and pass TAVV (Cryptogram), last four digits and par parameter as part of additional_info JSON. There is no change in the response and it remains the same.

📘

Note:

The par parameter is optional as part of additional_info JSON.

Note:

tokenReferenceid field is required in the additional_info parameter if you are provisioning Alt ID outside PayU for Diners card.
