India Payment Gateway

Accept UPI, IMPS, NEFT and RTGS through one enterprise API

By PayEurasia Payments TeamLast updated

India runs the largest real-time payment network in the world, and the overwhelming majority of that volume never touches a card network. If your checkout in India is card-first, you are not competing on price or product — you are competing with a payment instrument most of your customers simply do not use for online purchases.

PayEurasia is an India payment gateway engineered for merchants with demanding requirements: full domestic rail coverage, real-time transaction visibility, reconciliation-grade reporting, redundant routing and a compliance team that understands complex verticals. This page explains the rails, the API model, settlement and how to get live.

Payment methods

Domestic rails your customers already use

Every Indian rail has a distinct role. Choosing the right one per transaction type is what separates a checkout that converts from one that leaks customers at the final step.

UPI

Instant, account-to-account collection through QR or intent flows. The default rail for consumer payments across every state and income band.

IMPS

Immediate interbank transfer available around the clock, with instant credit. Strong mid-ticket rail and an effective fallback for UPI.

NEFT

Batch-settled bank transfer used widely for larger, non-urgent payments and recurring business settlement.

RTGS

Gross real-time settlement for high-value transfers where individual bank-grade settlement is required.

Bank transfer

Direct account collection with unique reference codes so every inbound payment maps to an order automatically.

Payouts

Disbursement to bank accounts and VPAs with the same idempotency and signed-webhook guarantees as collections.

How it works

From checkout to settlement in four steps

1. Create a transaction

Your backend calls the PayEurasia transactions API with amount, currency, method and an idempotency key, and receives a transaction reference plus the payment instruction immediately.

2. The customer pays locally

The customer completes the payment in their UPI app, initiates an IMPS transfer, or sends a NEFT or RTGS payment using the reference returned by the API.

3. Webhook confirmation

PayEurasia emits an HMAC-signed webhook the moment the payment state changes, so your ledger stays synchronised without polling. Delivery is at-least-once — verify the signature and keep the handler idempotent.

4. Settlement and reporting

Confirmed volume enters your merchant balance. Settlements, fees and commission lines are exportable per period for finance reconciliation against your own records.

Developer API

A payment processing API built for production

Payment integrations fail in the edge cases, not the happy path. The PayEurasia API is designed around the failure modes: duplicated requests, dropped responses, out-of-order notifications and partial states.

Idempotency keys

Every write accepts a key so a retried request returns the original result rather than creating a second transaction.

Stable references

One transaction reference from creation to settlement, usable across dashboards, webhooks, exports and support conversations.

HMAC-signed webhooks

Signature verification with a shared secret, replay protection and automatic retry with backoff on failure.

Full sandbox

A test environment that mirrors production state transitions, including failure and timeout scenarios you need to handle.

Explicit state model

Documented transaction states with a complete history per transaction, so you never have to infer what happened.

Clear errors

Structured error codes with actionable messages instead of opaque generic failures.

Industries

Built for merchants mainstream processors decline

High risk does not mean unsupported. It means your payment partner needs stronger monitoring, clearer risk rules and redundancy across providers — which is exactly how PayEurasia is architected. Read more about our approach on the high-risk merchant payment processing page.

FAQ

Frequently asked questions

What is an India payment gateway?

An India payment gateway is the infrastructure that lets a business collect payments from Indian customers over domestic rails — UPI, IMPS, NEFT, RTGS and bank transfer — confirm those payments programmatically and settle the funds to the merchant. PayEurasia provides that acceptance layer together with reconciliation, reporting and payout tooling behind a single REST API.

Which methods should I enable first?

UPI covers the widest consumer base and confirms instantly, so it is the default primary rail for consumer ticket sizes. IMPS is the natural companion for mid-ticket and as a fallback, while NEFT and RTGS cover larger and business-to-business transfers.

How quickly are UPI payments confirmed?

UPI is a real-time rail, so successful collections typically confirm within seconds. PayEurasia pushes an HMAC-signed webhook as soon as the state changes, so your order system updates without polling.

How does settlement work in India?

Confirmed volume moves into your merchant balance in INR. Settlement cadence, currency and any reserve terms are agreed during onboarding based on volume and vertical, and every settlement, fee and commission line is visible and exportable in the merchant portal.

Do you support high-risk merchants in India?

Yes. Forex, iGaming, betting, gaming, SaaS, digital services and subscription businesses are core verticals for us. Each merchant is underwritten individually rather than declined on category.

How long does integration take?

Most engineering teams complete the integration in a few days. You receive sandbox credentials, idempotent transaction endpoints, HMAC-signed webhooks and reference payloads before go-live.

What happens if a provider goes down?

PayEurasia maintains parallel provider capacity per method and monitors route health continuously. Traffic shifts automatically to a healthy provider so checkout remains available while the primary recovers.
