Net Banking Payment Experience

Suggest Edits

Net Banking recurring like cards are processed seamlessly without the customer’s intervention and any 2FA.
There are two common terms in Net Banking recurring:

  • Registration transaction(also known as e-Mandate transaction)
  • Payment transaction (also known as e-NACH transaction or SI transaction).

📘

Note:

Effective from 1st April 2024, mandates can be issued for a maximum duration of 40 years from the date of issuance.

Registration transaction workflow

The steps involved in a registration transaction (e-Mandate) are:

  1. This is usually an INR 0.00 (zero rupee) transaction hence it is called a registration transaction.

📘

Notes:

  • Upfront payment can be collected only through direct integration – HDFC Bank and ICICI Bank. For all the 40+ banks supported through NPCI, you cannot collect the upfront amount and perform only the INR 0.00 authentication.
  • Upfront payment can be collected only through direct integration – HDFC Bank(₹1 Lakh) and ICICI Bank.
  1. Merchant presents an option to sign up for a recurring platform where the customer needs to provide his/her consent.
  2. Billing details like amount, frequency, start date, and end date of the subscription need to be presented to the customer and passed to PayU during payment request.
  3. On redirecting to PayU:
    • Non-Seamless Integration: The customer selects preferred bank and enters account details like account number, name of the account, and account type: Savings or Current.
    • Seamless Integration: Merchant has to send all the parameters, that is, preferred bank, account number, name of the account, and account type.

  1. The customer is redirected to the any of the following based on authentication selected:
    1. Bank’s login page and authenticates himself with either net banking username and password or debit card number and ATM PIN depending upon the preferred bank.
    2. NPCI page for the Aadhaar authentication. For more information, refer to eNACH Aadhaar Authentication.
  2. On successful authentication, the customer sees registration details like billing amount, billing frequency, start date, and end date of the subscription plan.
  3. The customer approves the subscription details from the bank page and gets redirected back to PayU. At this stage, the bank can approve the registration request by returning the “Success” response to PayU or reject the same with the “Failed” response.
  4. On receiving either of the response from the bank, the same is communicated back to the merchant on a real-time basis.

eNACH Aadhaar Authentication

In Step 5 above, the customer is redirected to NPCI page for the Aadhaar authentication, so the additional steps involved for Aadhaar authentication are:

  1. Customer enter their Aadhaar card number in the Aadhaar Card Number field and clicks Confirm.
  1. Customer enter the OTP in the OTP and Confirm OTP fields that is received to the mobile phone registered with Aadhaar, and then clicks Continue.
  1. Customer enter the OTP that is sent by to bank to the registered mobile number and clicks Continue.

The transaction status is displayed similar to the following screenshot:

Recurring transaction workflow

The steps to perform a recurring transaction for Net Banking are:

  1. After registration is successful, the merchant can call the recurring payment API of PayU by passing the unique PayU ID received in the response to the registration transaction.
  2. All the transaction requests coming from the merchant are queued and forwarded to acquirers through a file. This is performed since most of the time even payment processing for Net Banking recurring is offline.
  3. The real-time response for Recurring transactions to the merchant is always returned as Pending. For direct integration with ICICI bank, the response will be real-time.
  4. For NPCI-supported banks and HDFC direct Integration, the response of the transaction is received over SFTP from acquirers at the end of the day, which is then stored in PayU’s DB, and the same is communicated to the merchant over a webhook API call.
  5. TAT for receiving either Success or Failure case of e-NACH transactions is T+2 similar to the registration transaction.
