What orchestration actually does
An orchestration platform connects to many acquirers and payment methods through one integration. You set rules, for example sending cards from one region to the acquirer with the best acceptance there, sending high value orders through stronger 3-D Secure, or capping how much volume each acquirer receives per month.
If a transaction is declined for a technical or soft reason, cascading can retry it through another acquirer. If an acquirer goes down or closes your account, its route is switched off and traffic flows to the others. Because tokens sit in the orchestration vault, saved cards keep working whichever acquirer processes them.
