How smart routing increases conversion rates

Two acquirers rarely approve the same traffic equally. Approval rates vary by card BIN, issuer, amount, time of day, and the acquirer’s current health. A static single-acquirer setup leaves money on the table.

Smart routing scores candidate paths in real time and sends each transaction where it is most likely to be approved. A self-learning model balances exploiting known-good routes with exploring alternatives as conditions shift.

On decline, cascading failover retries on an alternate acquirer within milliseconds — split into pre-3DS and post-3DS phases so step-up is never wasted.

The result is a measurable uplift in authorization rate, with full traceability on why each route was chosen.
