Frequently Asked Questions
Use payment gateways like Razorpay, Cashfree, or PayU that provide UPI integration via APIs. They handle the complexity of UPI protocol, bank connections, and settlement. Integration typically takes 1-2 days with their SDKs. Direct NPCI integration is possible but requires bank partnership and is only justified at very high volumes.
UPI is expanding internationally — it works in Singapore, UAE, France, Sri Lanka, and several other countries via partnerships. UPI International allows Indians to pay abroad, and soon foreign users will be able to make UPI payments in India. This creates opportunities for cross-border fintech solutions.
