A:
First, start by mapping your merchant categories (MCCs) or business use cases to the NPCI’s standardized UPI purpose codes. For credit card bill payments, the typical purpose code is something like CCP (Credit Card Payment) or whatever your PSP/bank mandates under NPCI’s Credit Card Repayments category. Your PSP should provide an updated list after the September 2025 changes.
Then, when your marketplace platform generates a UPI collect or intent request (like through Razorpay, Paytm, or Pine Labs APIs), inject the purposeCode field directly into the payload — for example:
{
txnId: TXN12345,
amount: 50000,
payerVPA: user@upi,
payeeVPA: creditcard@bank,
purposeCode: CCP,
note: Credit Card Bill Payment
}
This makes the transaction self-identifying during audits, so both your system and the PSP know it’s a credit card bill payment and not a generic transfer.
On the backend, make sure the ledger and reconciliation modules also carry this code. When you export daily reports or settlement files, include the purpose code in a dedicated column (e.g., UPI Purpose Code) so finance and compliance can filter these transactions instantly.
You can even go one step further: set up a rule in your payments orchestration layer — if the payee VPA belongs to a recognized credit card issuer (like @hdfcbank, @icicibank, etc.), automatically tag it with the CCP purpose code. That reduces manual tagging errors and ensures every bill payment gets the right classification, even when customers use third-party apps to initiate UPI payments
