UPI error YI: Invalid response code
Raised by: Bank / PSP. Source: NPCI, UPI Error and Response Codes v2.9, section 3.1, codes populated by banks and PSPs.
What it means
A bank returned a response code that isn't valid for this API. The real reason was lost because the code couldn't be mapped.
NPCI's list doesn't say at which step this code is raised. Most failed UPI payments are not debited; check your statement.
If you were debited and the payment failed, the money is due back by T+1 for a transfer to a person, or T+5 for a payment to a merchant.
Bank or PSP: it sent an unexpected code.
Business: the systems worked and declined the payment.
What you should do
Check your statement. If money left your account and the payment failed, it will be reversed. Then try again.
If you are a merchant, bank or PSP
Ask the bank which code it intended to send. YI points to a mapping problem in its integration.

If it still isn't sorted
- Raise a complaint inside your UPI app. Every UPI app has a help or dispute option on the transaction, and it goes into NPCI's online dispute system. Keep the UPI transaction ID or RRN handy.
- If the app doesn't resolve it, contact your bank's grievance desk with the same reference.
- If your bank hasn't replied within 30 days, or you're not happy with the reply, complain to the RBI Ombudsman at cms.rbi.org.in. It's free.
Technical or business decline?
NPCI splits declines into two kinds. A technical decline means a system didn't respond or failed: a bank offline, a timeout, a switch error. A business decline means the systems worked and said no, for a reason about the account or the payment: wrong PIN, not enough money, a limit, a risk check. Retrying helps with some technical declines and almost never with business ones.
