This video explains how a payment gateway works — the invisible layer between your customer clicking "Pay Now" and the money landing in your bank account. It covers the full flow: card or UPI details are encrypted, sent to the gateway, verified by the issuing bank, and settled into your merchant account.

As a Commerce Synapse seller, your store connects to Razorpay as its payment gateway. Understanding this flow helps you troubleshoot failed transactions, explain refund timelines to customers, and choose the right payment methods (UPI, cards, netbanking, wallets) for your audience.
