Build incredible payment experiences. Integrate the fastest UPI API with zero commission, flat pricing, and a native no redirect checkout.
The UPI Checkout API is your technical bridge to the fastest-growing payment network in the world. Instead of using off-the-shelf links, the API lets developers programmatically generate dynamic QRs, trigger payment intents, and handle webhook confirmations instantly within their own app architecture.
For growing platforms, D2C brands, and SaaS companies in India, relying on manual payment verification is impossible. You need a payment gateway that scales with your code. Most APIs come with heavy SDKs that take days to integrate and charge a heavy percentage fee for the privilege. Modern developers need an API that is lightweight, highly reliable, and cost-effective.
SMEPay offers a robust REST API engineered for speed. By operating on a zero commission model, our API ensures that as your transaction volume spikes, your fees remain a predictable, flat rate. Most importantly, our API naturally enforces a no redirect checkout flow on mobile devices, launching the user's UPI app directly via deep links rather than bouncing them across browser windows.
