New Delhi, April 29 || In the wake of the mega unified payments interface (UPI) outage earlier this month, the National Payments Corporation of India (NPCI) has asked banks to ensure that all the API requests (traffic) sent to UPI is monitored and moderated in terms of appropriate usage.
The relentless transaction status checks by banks resulted in the massive UPI outage on April 12, leaving millions stranded.
In a notification, the NPCI has said that banks will initiate the first check transaction status API after 90 seconds from the initiation/authentication of the original transaction.
“After the timers are changed, members may initiate the same after 45 to 60 seconds of the initiation/authentication of original transaction, after NPCI revised communication,” said the agency.
Banks may initiate maximum of three check transaction status APls, preferably within two hours from the initiation/authentication of the original transaction, it added.
Payment service provider banks will ensure that all the API requests (traffic) sent to UPI is monitored and moderated in terms of appropriate usage -- for restricting high number of repeat APIs for same transactions or older transactions, etc.
