How UPI Payments Work for Online Businesses
·6 min read
UPI connects bank accounts and PSPs through NPCI’s infrastructure. Online, the customer authorises in their UPI app; the merchant side learns success through PSP notifications or gateway webhooks.
Operational takeaway
Your website should never assume instant success—treat payment as asynchronous until verified. VyaparGateway helps you issue dynamic UPI QR codes, verify payments, and notify your stack via webhooks—without charging a per-transaction platform fee on top of your plan.
