NexaPay — The Gateway That Never Fails

NexaPay is the world's most reliable payment gateway. Built on a distributed, multi-region architecture with automatic failover, NexaPay delivers 99.999% uptime and processes payments in an average of 187ms — even at peak loads of 50,000 transactions per second.

Unlike legacy gateways that send you to a single acquiring bank, NexaPay routes each transaction through an intelligent network of 14 global acquirers, selecting the optimal path based on transaction type, currency, location, and real-time success probability scores.

Intelligent Routing 14 Acquirers 135+ Currencies 80+ Methods 3DS2 Tokenisation
Smart Retry Logic

ML models predict optimal retry timing for declined transactions, recovering up to 15% of soft declines automatically.

Real-Time Webhooks

Instant payment status notifications via webhooks with guaranteed delivery and automatic retry for failed deliveries.

Network Tokenisation

Replace card details with network tokens for higher approval rates and zero-liability chargeback protection.
