What is UPI Autopay?
UPI Autopay, launched by NPCI, empowers companies to receive recurring payments directly from customers' UPI-linked bank accounts. Customers create e-mandates through UPI apps such as Google Pay, PhonePe, Paytm, and BHIM, which trigger automated debits without human intervention. Castler’s UPI Autopay supports seamless collections through Payin APIs. For end-to-end fund flows, Payout APIs can be used separately for disbursals or refunds.
