Payment gateway integration
From gateway setup to a checkout that reconciles on its own. Here is how we configure, build and monitor a payment gateway integration.
Core process
We set up sandbox and live gateway accounts, generate the right API keys, and register webhook endpoints so every event the gateway sends has somewhere to land before checkout work begins.
Checkout, authorization handling, webhook processing and refund logic are built together rather than as separate afterthoughts, so a refund or a failed webhook is handled the same way as the original payment.
Before launch, we test declines, retries, disputes and refunds against sandbox scenarios. After go-live, we monitor real transactions and reconciliation for the first cycle to confirm the ledger matches the gateway's records.
Gateway accounts, keys and webhooks configured before any code ships.
Checkout, webhooks and refunds built as one connected flow.
Testing, launch and reconciliation monitoring after go-live.
A tested checkout flow built on the gateway's current API.
Stripe, Razorpay, PayPal or others behind one interface.
Every event verified, logged and retried on failure.
Full and partial refunds handled as first-class flows.
Settlement events post directly into your accounting ledger.
Alerts on failed webhooks or unusual decline rates.
No. The integration is built alongside your ERP as a separate layer, not a replacement or a core modification. Your ERP keeps working exactly as it does today.
Every integration includes error handling and alerts, so failed syncs and mismatched records are flagged and logged rather than silently lost. We review and resolve flagged issues as part of ongoing support.
Yes. We monitor live integrations, handle new sync errors, and adjust field mappings as your systems or business processes change.
