@ErBhautik this is related to your transaction quota, maybe quota for specific to the merchant or your UPI.

@ErBhautik this is related to your transaction quota, maybe quota for specific to the merchant or your UPI.

This is happening for other upi as well.This is something related to privacy.

For phone pay I'm getting error that you are not allowed to send money from your bank For this transaction.

For paytm I'm getting error that payment mode is not allowed for this UPI ID.

For BhIM upi I got the error RISK THRESOLD EXCEEDED.
