RS Marketing & Solutions

What's included

Everything that goes into a payment integration

A checkout button is the easy part — this is everything that has to work correctly behind it before real money moves.

Multiple Gateway Support

Razorpay, Stripe, PayPal, PayU, CCAvenue or Cashfree — integrated individually or offered together as customer choices at checkout.

Secure API Integration

Server-side API integration with keys kept off the frontend, so sensitive payment data never touches an insecure path.

PCI-DSS Compliant Setup

Checkout built to PCI-DSS standards using hosted fields or redirect flows, so you're not storing raw card data yourself.

Multi-Currency Support

International currency support configured where your gateway allows it, so overseas customers can pay in their own currency.

Automated Payment Verification

Server-side signature verification on every transaction, so orders only confirm once payment is actually verified.

Refund & Webhook Handling

Webhooks wired in for payment status updates, refunds and failed-payment retries, handled automatically instead of manually.

One integration, every major gateway your customers actually use

Different customers trust different gateways — UPI-first shoppers want Razorpay or Paytm, international customers expect Stripe or PayPal. We integrate the ones that match your actual audience.

Razorpay & Paytm for UPI, cards and net banking in India
Stripe & PayPal for international card and wallet payments
PayU, CCAvenue & Cashfree as India-focused alternatives with local support

Technologies we use

The gateways and tools we integrate

Chosen based on your market and business type — a domestic store and a global SaaS product need different gateways.

Our process

How a payment gateway goes from setup to live

The same six steps on every integration, in order, so no gateway ever goes live untested.

1

Gateway Selection & Account Setup

We help you choose the right gateway for your market, then set up the merchant account and business KYC documents.

2

API Keys & Sandbox Testing

Test-mode API keys wired into a sandbox checkout, so every flow is tried safely before any real money is involved.

3

Checkout Integration

The gateway is built into your actual checkout flow — cart, order summary, payment step and confirmation — end to end.

4

Security & Compliance Check

Signature verification, HTTPS enforcement and PCI-DSS-aligned handling checked before moving out of sandbox.

5

Live Mode Activation

Live API keys swapped in, a real low-value transaction is tested, and the gateway goes fully live on your site.

6

Post-Launch Monitoring

Webhook delivery, failed payments and refund flows monitored after launch, with fixes handled quickly if anything misfires.

FAQs

Common questions about payment gateway integration

Still unsure about something? Ask us directly in the form and we'll cover it in our reply.

Which payment gateways can you integrate?

We integrate Razorpay, Stripe, PayPal, PayU, CCAvenue, Cashfree, Paytm, Instamojo and Braintree, and can work with other gateways your business already uses on request.

Do I need a separate merchant account with the gateway?

Yes, the merchant account and KYC verification is set up directly with the gateway provider under your business — we guide you through that step and then handle the technical integration.

Is it safe to store card details on my server?

We build checkout using hosted fields or redirect flows so your server never touches raw card data, keeping you out of the heaviest PCI-DSS compliance requirements.

How long does a payment gateway integration take?

A single gateway integration typically takes 1 to 3 weeks including sandbox testing, depending on your existing checkout flow and how many currencies or payment methods are needed.

Can you add multiple gateways so customers can choose?

Yes, we regularly integrate two or more gateways together, letting customers pick their preferred payment method at checkout.

What happens if a payment fails or needs a refund?

We wire in webhooks for failed payments and refund status, so your system updates automatically instead of needing manual checks against the gateway dashboard.

Accept payments safely, on whichever gateway your customers trust
