UPI Payment Gateway

Real-time collections from India's dominant payment rail

UPI processes billions of transactions a month and has become the default way Indian consumers pay. A checkout without UPI is a checkout most Indian customers will abandon.

PayEurasia provides a UPI acceptance layer engineered for volume: instant confirmation, deterministic retries, provider redundancy and finance-grade reporting.

Advantages

Why UPI outperforms cards in India

Instant settlement signal

Confirmation arrives in seconds, so digital goods can be released immediately.

Universal adoption

Supported by effectively every major Indian bank and consumer payment app.

Low friction

No card details, no 3DS step-up, far fewer abandoned checkouts.

Lower failure rates

Domestic rails avoid the cross-border decline patterns that hit international cards.

Engineering

What the integration looks like

Create the collection

POST a transaction with amount, method UPI and an idempotency key; receive a reference and payment instructions.

Handle the webhook

Verify the HMAC signature, match on the transaction reference and update your ledger. Retries are automatic and logged.

Reconcile

Query the transactions API or export statements to align your books with settled volume, fees and commissions.

Reliability

Designed to stay up under load

Automatic failover

Health checks pull traffic away from degraded providers without manual intervention.

Idempotency

Safe retries under flaky mobile networks — never a duplicate charge.

Operational visibility

Success rate, latency and error breakdowns per provider in real time.

Add UPI to your checkout

Apply as a merchant and get sandbox credentials, reference payloads and a go-live plan for UPI collections in India.

FAQ

Frequently asked questions

What is a UPI payment gateway?

A UPI payment gateway lets a business initiate and collect Unified Payments Interface transactions from Indian customers, receive confirmation programmatically and settle the proceeds to a merchant account.

How fast is UPI confirmation?

UPI is a real-time rail — payments typically confirm within seconds, and PayEurasia pushes the state change to your webhook endpoint as soon as it lands.

Can high-risk merchants use UPI through PayEurasia?

Yes. We onboard merchants in verticals such as Forex, iGaming, digital services and subscription platforms, subject to KYB review and risk configuration.

What happens if a UPI payment fails?

Failures return a reason code through the API and webhook. Idempotency keys make a safe retry straightforward, and routing can shift the attempt to another provider.

Do you support refunds on UPI?

Refund states are modelled in the transaction lifecycle and surfaced in the merchant portal and API for reconciliation.

Can UPI be combined with IMPS, NEFT and RTGS?

Yes. Most merchants enable UPI for consumer-size payments and keep IMPS, NEFT or RTGS available for higher-value transfers.
