Payment Gateway Integration

Reliable money movement on the web

Webhook discipline, retries, and admin visibility into payment states.

Payments fail in edge cases—network drops, bank timeouts, duplicate callbacks. Engineering must be idempotent and observable.

We integrate hosted checkouts or APIs, sign webhook payloads, and align order states with your CRM or ERP where applicable.

Gateway wiring: keys per environment, rotation runbooks, and least-privilege access.
Webhooks: signature verification, retry-safe handlers, and dead-letter logging.
UX: clear pending/success/failure screens and support-friendly references.
Reconciliation: CSV/API exports for finance close processes.
Compliance posture: PCI SAQ-A patterns for hosted flows; deeper scopes when needed.

Race conditions and double charges addressed in design reviews.

Dashboards or logs your team can interpret without reading code.

Readable typography, touch targets, and breakpoints tested on real devices—not guesswork.

DNS, SSL, redirects, analytics, backups, and handover docs so your team can operate confidently.
