Payment Gateway Integration
Payment gateway integration is the work of connecting your website or app to a payment processor like Stripe, PayPal, or Razorpay so customers can actually pay you, securely and reliably. We handle the setup, API integration, and testing needed to get transactions processing correctly.
This covers account and API key setup, checkout flow implementation, handling webhooks for payment confirmation and failures, and making sure sensitive card data never touches your own servers unnecessarily. We also account for the practical details — currency support, refund handling, and recurring billing where relevant — so the integration holds up in real-world use, not just in testing.
Gateway Setup & API Integration
Stripe, PayPal, Razorpay, or other provider accounts connected to your site through their official APIs and SDKs.
Secure Checkout Flow
Checkout built to keep sensitive payment data handled by the gateway itself, reducing your PCI compliance burden.
Webhook & Transaction Handling
Payment confirmations, failures, and refunds handled through webhooks so your order records stay accurate automatically.
Recurring Billing & Multi-Currency
Subscription billing and multi-currency support configured where your business model needs them.
How it Works
Requirements Review
We confirm which gateways, currencies, and billing models (one-time, recurring, or both) your business needs.

Integration & Configuration
We connect the gateway APIs, build the checkout flow, and set up webhook handling for payment events.
Testing & Go-Live
We test transactions, refunds, and failure cases in sandbox mode before switching the integration to live payments.

Frequently Asked Questions
Generally no — we design integrations so card data is handled directly by the payment gateway rather than stored on your servers, which keeps your PCI compliance scope much smaller.
Yes, it's common to offer more than one option, such as Stripe alongside PayPal or a regional provider like Razorpay, and we can wire up multiple gateways on the same checkout.
It depends on how many gateways you need and how complex your checkout or billing logic is. A single standard integration is quicker than one involving subscriptions or multiple currencies.
It depends on the number of gateways, currencies, and billing features involved. Contact us for a quote once we understand your requirements.
Accounts (or the intent to create them) with your chosen gateway providers, details on the currencies and payment methods you want to support, and admin access to your website or app codebase.
We stay available for fixes right after go-live, and ongoing monitoring can be arranged separately — payment integrations generally need less ongoing work than other services once stable, but gateway API changes do occasionally require updates.
