API Development & Systems Integration
Payment Gateway Integration
Integrate Indian and international payment gateways into your website, app or billing system, with secure checkout, webhooks, refunds and reconciliation handled properly.
Overview
Why it matters
for your business.
Accepting payments online involves more than adding a checkout button. You need to verify payments on the server, handle UPI and card failures, process refunds, manage recurring mandates and reconcile settlements with orders and invoices. Mistakes lead to unpaid orders marked as paid, or angry customers charged twice. We integrate payment gateways into your existing platform so every rupee is accounted for.
We help you choose a gateway based on your payment mix, settlement needs and any international requirements, then implement it using the provider’s recommended flows. Payment status is always confirmed through signed webhooks and server-side verification. Refunds, partial captures and subscriptions are tested in sandbox before going live. Settlement reports are matched against your orders so finance can reconcile accounts without spreadsheets.

FAQ
Common
questions.
Something else on your mind? Ask us directly.
Which payment gateway should we choose?
It depends on your payment methods, ticket sizes, settlement timelines, international needs, subscription requirements and the pricing you negotiate. We compare suitable options based on your requirements rather than any vendor preference. Many businesses also keep a second gateway as a fallback for resilience.
Do we need PCI DSS compliance if we accept card payments?
If you use a gateway’s hosted checkout or tokenised SDK, card data never touches your servers, which keeps your compliance scope small. You will usually still complete a self-assessment questionnaire. We design the integration to keep sensitive data with the gateway and avoid storing card details ourselves.
