Payment Gateway Integration
Take payments online through the gateway you already use
Payment Gateway Integration
In India, online payments usually go through Razorpay, PayU or Cashfree, with Stripe or PayPal as options for customers paying from abroad. We integrate these gateways into web and mobile apps and into WordPress and WooCommerce sites. If you already have a gateway account, we work with that one. Customers enter their card or UPI details in the gateway's checkout, so card data stays with the gateway. On your side, we confirm each payment on the server, handle webhooks for late or failed payments, and keep your records in step with the gateway's.
What We Deliver
What's included in Payment Gateway Integration.
The payment methods customers use
UPI, cards, netbanking and wallets through the gateway's checkout, on your website or inside your mobile app.
Card data stays with the gateway
We use the gateway's hosted or embedded checkout, so card details are entered on the gateway's form and not stored on your server.
Subscriptions and recurring payments
Plans, renewals and retries using the gateway's subscription features, including UPI AutoPay and card mandates where your gateway supports them.
Webhooks and reconciliation
Signed webhook handlers that record captured, failed and refunded payments, plus a check against the gateway's records to find anything that doesn't match.
Server-side verification
Each payment is confirmed on your server with the gateway's signature or API before an order is marked paid, rather than trusting what the browser reports.
Refunds and payouts
Full and partial refunds from your admin panel, and split payments or vendor payouts where your gateway offers them.
Our Process
How the work runs, step by step.
Requirements
We list the payment methods you need, one-time or recurring payments, refunds and payouts, and confirm which gateway account you'll use.
Integrate
We build the checkout, the server-side verification and the order updates into your app or site.
Webhooks
We set up signed webhook handlers for successful, failed and refunded payments and for subscription events.
Test in sandbox
We run successful, declined, abandoned and refunded payments in the gateway's test mode before any real money moves.
Go live
We switch to live keys, check the first real payments with you, and set up alerts for failed payments and webhook errors.
Frequently Asked Questions
Common questions about Payment Gateway Integration.
Razorpay, PayU, Cashfree, Stripe and PayPal. Other gateways are possible if they have a documented API, and we'll check before quoting. If you already have a merchant account, we integrate that one. If you're still choosing, we can compare fees, settlement times and payment methods with you.
No integration makes a business compliant on its own. With the gateway's hosted or embedded checkout, card details are entered on the gateway's side and not stored on your server, which leaves the handling of card data to the gateway. Your gateway can tell you what, if anything, it needs from you.
We confirm each payment on the server, and handle the gateway's webhooks so a payment completed after the customer closed the page still gets recorded. The handlers recognise repeated notifications so they don't create a second order. A reconciliation check against the gateway's records then flags anything that doesn't match, so it gets fixed instead of going unnoticed.
Yes, if your gateway supports it. Recurring payments in India run on mandates, such as UPI AutoPay or card e-mandates, which the customer approves once. We build the plans, renewals and failed-payment handling around your gateway's subscription features.
Typically one to two weeks, depending on scope, for one gateway with one-time payments and webhooks. Subscriptions, a second gateway or payouts add time. We confirm the timeline once the requirements are clear.
