Guides on API integration for payment systems: REST/JSON endpoints, SDKs, and webhooks for core flows (auth, capture, refund/void, payout), tokenization & vaulting, 3DS/EMV 3-D Secure, idempotency keys, retries/backoff, HMAC signatures and webhook verification, versioning, and observability (logs, alerting).
We cover gateway vs. orchestration layers, multi-acquirer routing, reconciliation via reports/webhooks, and PCI DSS scope reduction (card-data minimization, SAQ types). For high-risk merchants (iGaming, FX/CFD, adult, crypto), we highlight onboarding constraints, risk flags, velocity checks, and failover strategies to keep approval rates stable under stricter controls.
