Payment Routing: каскадирование платежей

Payment routing — динамический выбор acquirer для каждой транзакции, критично для approval rate и cost.

Cascading

Первичный acquirer declines → auto retry через альтернативный. Разные BIN prefixes → разные acquirers. Currency-based routing: EUR через EU acquirer, USD через US. Behavioral rules: high-risk → specialized processor.

Метрики

Approval rate: % successful auth. Baseline: 75–85% для gambling. Оптимизация: 90%+. Cost per successful transaction: total fees / approved amount. Time to approval: latency каждой попытки. Chargeback rate по каждому acquirer.

Smart routing algorithms

Rules-based: card type, geo, amount → acquirer. ML-based: features (BIN, time, device) → predicted best acquirer. A/B testing splits. Recovery flows: 3DS challenge как fallback. Deep learning: LSTM для sequence-based prediction.

Providers

Payment orchestration: Corefy, Praxis, Yuno, IXOPAY. Собственная разработка: complex, 6+ months. Cost: revenue share или fixed fee. Benefit: 5–15% uplift в approval, что напрямую = revenue. Обязательно для scale.
