Intelligent routing, also called smart routing, refers to payment transaction routing that uses real-time performance analytics, statistical modeling, or machine learning to select the optimal gateway or processor for each transaction, rather than relying solely on static rules or manual configuration. It represents the more sophisticated end of the Dynamic Routing spectrum.
While all dynamic routing responds to real-time data to some degree, intelligent routing systems go further: they learn from transaction outcomes, identify patterns that human-configured rules might miss, and adapt routing logic automatically as gateway performance changes. A smart routing system might identify, for example, that authorization rates for a specific BIN (Bank Identification Number) range improve on a particular gateway at certain times of day, or that a new gateway outperforms established providers for a specific card category, and adjust routing accordingly without manual intervention.
The distinction between rule-based dynamic routing and intelligent routing is one of degree rather than kind, and the industry uses the terms interchangeably in many contexts. Rule-based dynamic routing is explicit: rules are configured by humans based on observed performance data. Intelligent routing is adaptive: the system derives and updates its own routing logic from the transaction data stream. In practice, most enterprise routing implementations combine both approaches, human-configured rules for known, stable patterns, and adaptive optimization for emerging or complex patterns.
For merchants, the practical question is not which label to apply but what performance improvement the routing system delivers. Spreedly's platform provides the data infrastructure, transaction-level performance reporting, authorization rate analytics by gateway and card type, that enables both rule-based and increasingly sophisticated routing optimization.
