One operational layer

Infrastructure that keeps every payment traceable.

UPI Pay gives businesses a clean software layer around their approved payment-provider connection.

↗

Merchant connections

Keep provider credentials encrypted and isolated for each merchant account. Connections activate only after provider approval.

How our model works →

Dynamic payment orders

Create amount-specific payment sessions with your own order references and customer context.

✓

Verified payment status

Do not trust a browser redirect. Confirm payment state from the provider before fulfilling an order.

{ }

Signed webhooks

Deliver event payloads to merchant systems with signatures, timestamps and replay-aware processing.

How it works

A clear path from onboarding to confirmation.

Verify the merchant

Business and KYC details are reviewed by the contracted payment infrastructure provider.

Connect securely

The approved merchant connection is stored encrypted and separated from other accounts.

Create an order

Your website or app calls one authenticated endpoint with the amount and order reference.

Confirm and fulfil

A provider-verified event updates the order before your system delivers goods or access.

Payment features and settlement are subject to partner availability, merchant KYC, risk review and the terms of the contracted provider.

Built for developers

One API surface. Your product experience.

Use UPI Pay from PHP, Laravel, WordPress, Android or any backend that can make HTTPS requests. API keys are hashed, requests are authenticated, and sensitive provider credentials stay encrypted.

Idempotent order references
