NPCI directs UPI members to follow new API guidelines to avoid disruptions

The National Payments Corporation of India (NPCI) has directed members of the unified payments interface (UPI) network to adhere to its guidelines on application programming interface (API) calls, whose overuse resulted in an outage of the real-time payments system earlier this month.

APIs are sets of protocols and tools that enable secure data exchanges between banking systems and the UPI network.
