One platform to control all your payments.
Route transactions across 100+ providers — crypto and fiat. Optimize success rates, reduce costs, and control risk in real time.
Built for both engineering teams and finance leads. A REST API, a multi-tenant admin cabinet, a developer sandbox, and a spec-driven PHP SDK — everything needed to accept, route, and reconcile payments without owning the infrastructure.
Pick the optimal provider by priority, payway, currency, and failover chain. Routing rules are configurable per merchant, per direction.
Automatic failover with exponential backoff. CLOSED → OPEN → HALF_OPEN recovery keeps traffic off unhealthy providers.
X-Idempotency-Key with 24h TTL and SHA-256 payload match. No duplicate charges, even during retry storms.
HMAC-verified PSP callbacks with IP-whitelist and signature validation. Webhook delivery with up to 5 exponential-backoff retries.
One integration for fiat rails (cards, SBP, SEPA, P2P) and blockchain (BTC, ETH, USDT, TON, TRX, SOL, and more). Switch providers without rewriting checkout.
SLI/SLO tracking with 99.5% targets and release gates. Structured error envelopes, slow-query logs, request tracing, and Prometheus-ready metrics.
From high-volume marketplaces to subscription SaaS, regulated iGaming to crypto-first fintech — Paynexus adapts to the shape of your business. Each use case ships with curated routing, pre-wired compliance, and dedicated integration patterns.
Split payments, escrow, delayed payouts, and seller KYC across thousands of counterparties. Ship faster without becoming a money transmitter.
Smart dunning, card account updater, proration, and multi-attempt retries. Recover 10–30% of involuntary churn without touching billing code.
Local acquiring, APMs, BNPL, and 3DS orchestration across 40+ markets. One integration — hundreds of payment methods, best conversion per geo.
Micro-payments with batched settlement, in-game wallets, chargeback liability shift, and creator payouts in crypto or fiat.
High-frequency deposits, instant P2P and crypto payouts, integrated AML, and routing built for MCC-sensitive merchants. Battle-tested at casino scale.
Card issuing, open banking, and programmable money movement — behind one modular SDK. Embed finance without rebuilding the rails.
Pre-built, certified, and maintained PSP connections — from live integrations like Piastrix, Ampay, Betterbro, and Unlimit to planned additions like CoinsPaid, Stripe, and BTC Pay. Both fiat rails and crypto processors, behind a single interface.
REST API with idempotent endpoints, signed callbacks, and full sandbox parity. A spec-driven PHP SDK lets you add new providers in hours — no framework lock-in, PHP 7.4+.
Full sandbox access is free — no card, no time limit. Scale to production with custom tiers: rate limits up to 10,000 req/min, 99.5%+ SLO, and a dedicated solutions engineer.
