How the Integration Gets Built
From gateway setup to a checkout that reconciles on its own. Here is how we configure, build and monitor a payment gateway integration.
Setup, build and go-live, in that order
Gateway accounts, keys and webhooks configured before any code ships
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.
- Sandbox and production accounts configured separately.
- Webhook endpoints registered and signature-verified.
- Currency, region and payout settings confirmed upfront.
Checkout, webhooks and refunds built as one connected flow
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 the original payment was.
- Checkout built against the gateway's current API.
- Webhook processing with signature checks and retries.
- Refunds and partial refunds built in from the start.
Testing, launch and reconciliation monitoring after go-live
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.
- Edge cases tested before anything goes live.
- Live transaction monitoring after launch.
- First reconciliation cycle checked against gateway reports.
