Stateless Architecture

We don't hold your money in intermediary wallets. Our infrastructure is designed for speed and direct settlement.

1. Generate

Send a POST request with the amount. We return a direct deep-link and QR mapped to your own Bank Account.

2. Direct Transfer

The user pays using FamPay or Slice. The money travels on NPCI rails directly into your bank instantly.

3. We only check if payment received or not

Our secure listener detects the incoming bank UTR. We simply check the transaction status and fire a cryptographically signed webhook to your server. Zero holds, zero friction.

Developer First

Engineered for Raw JavaScript.

No heavy frameworks or bloated SDKs required. Integrate directly into your frontend or backend using standalone JS. Easily process dynamic user-provided UPI addresses on the fly.

Founder Biography

Building the financial fabric for India's digital economy.

Vision & Mission

The journey of HeyUPI started with a singular observation: independent developers and creators were being unnecessarily taxed by legacy gateways that held their funds for days. As an engineer deeply passionate about open systems, the goal was to craft a purely technical layer.

"We believe software should liberate builders, not act as a tollbooth. Direct bank settlement isn't a feature; it's a right."

🇮🇳 Made in India

Engineered for the World's Fastest Network.

Built proudly on top of India's robust digital public infrastructure to empower independent developers and modern businesses without any gateway holds.
