UPI Payment Experience

Suggest Edits

Merchant performs the registration and mandate for UPI recurring payment with the UPI payment mode. The registration transaction is completed with 2FA, where the customer enters the MPIN (Mobile PIN) and authorizes the mandate details or billing details. After the registration transaction is successful, the merchant calls the recurring API to charge without further customer intervention.

UPI registration transaction workflow

The UPI registration is a mandated process. The UPI instrument provides total flexibility in designing the registration flow for merchants.

The steps involved in the UPI Registration transaction are:

  1. Merchant can deduct the first billing amount as part of the registration transaction and set up the recurring payments for subsequent transactions.
  2. Alternatively, the merchant can perform a small transaction minimum of 1 INR as part of the registration transaction and set up the recurring payments for subsequent transactions to the customer.
  3. Merchant presents the option to sign up for a recurring platform/subscription plan where the consent from customer is required.
  4. Billing details like amount, frequency, start date, and end date of the subscription need to be presented to the customer on the merchant’s website and passed to the PayU during registration transaction request over API interface.
  5. While redirecting to PayU, the customer enters the preferred VPA handle and proceeds with the transaction. If the customer’s Payment Service Provider (PSP) app is associated with VPA handle and the underlined bank account supports UPI recurring, the request will be received by the PSP app of the customer.

In case the customer’s PSP app and/or bank account associated with the VPA does not support UPI recurring, the transaction will be rejected.

  1. On receiving a request over the PSP app, the customer needs to approve the registration request by entering the MPIN.
  2. After successful authorization, the registration transaction gets completed and the response of the registration transaction along with the unique registration ID is returned to the merchant over browser redirection.

UPI recurring transaction workflow

The steps involved in a UPI recurring transaction are:

  • After the registration transaction is successful, the merchant can start calling the recurring payment API of PayU by passing a unique PayU ID received in the response to the registration transaction.
  • The merchant will be able to debit from the customer for the authorized billing amount without requiring any inputs or interventions from the customer.
  • However, before debiting the customer amount, it is mandatory to send a pre-debit notification to the customer informing them about the amount and debit date of the transaction. This needs to be sent at least 24 hours prior to actual debit. If the pre-debit notification is not sent successfully, the recurring transaction will fail. 
  • Since payment processing of UPI recurring is an asynchronous process with banks, real-time response for recurring transaction API is always returned as “Pending” if a valid request is passed by the merchant.
  • This state then gets converted into either “Success” or “Failure” once the bank confirms the status of the transaction to PayU over call back interface.
  • The merchant can either implement the Inquiry API or use PayU’s Webhook support to get the real-time status of the recurring transaction once the bank provides real-time confirmation.
