MERCHANT-CONTROLLED ROUTING
Control which eligible route is tried first.
Separate hard eligibility rules from commercial and performance preferences, then keep every route decision explainable.
When several PSP routes can process a payment, the merchant needs a policy that balances admissibility, conversion, cost, stability and available volume without turning routing into a black box.

Hard eligibility constraints
Determine whether a route may be used based on GEO, method, currency, amount, limits, traffic type and current availability.
Soft preferences
Order eligible routes using merchant priorities such as observed conversion, processing cost, stability or available volume.
Primary and fallback readiness
Distinguish configured routes from routes that are commercially approved, technically integrated and ready for production traffic.
A decision trail for every payment
See which route was selected, which rule applied and what provider response followed, so payment and support teams can investigate without guesswork.
[02] routing does not guarantee an outcome
Routing does not guarantee an outcome
A policy determines how eligible routes are selected; it does not guarantee provider availability, approval or conversion. Teams still need monitoring, investigation and controlled change.
[03] close the operating loop
Close the operating loop
Compare performance over time, detect degradation, investigate failure reasons and measure what changed after a route or priority adjustment.
