How it works
1
Shopper lands on product page
RabbitPay renders a Buy Now button next to your existing Add to Cart.
2
One tap + OTP
Returning shoppers authenticate via mobile OTP. First-time shoppers add their details once — future purchases become truly one-click.
3
Payment or COD selection
Shoppers pick full prepaid, partial COD, or full COD (with risk scoring).
4
Order created in Shopify
RabbitPay creates the order via the Shopify Admin API and fires webhooks to your systems.
