Routing Rules Using Two Payment Processors
In this example, the merchant uses two payment processors:- The merchant designates that 25% of transaction traffic should go to Processor A and the remainder should go to Processor B.
- CTS configures the first routing rule to specify that Processor A receives 25% of transaction traffic, and configures the default routing rule to specify that Processor B receives all other transaction traffic.
- Every credit card transaction has a 25% chance of being assigned to Processor A, and a 75% chance of being assigned to Processor B.
Routing Rules Using Three Payment Processors
In this example, the merchant uses three payment processors:- The merchant designates that 25% of transaction traffic should go to Processor A, 25% to Processor B, and the remainder to Processor C.
- CTS configures the first routing rule to specify that Processor A receives 25% of transaction traffic, then configures the second routing rule to specify that Processor B receives 33.3% of transaction traffic (one-third of the remaining 75% is 25% of the total), and configures the default routing rule to specify that Processor C receives all other transaction traffic (no % is needed for the default rule because all remaining transactions go to the default processor).
- Every credit card transaction has a 25% chance of being assigned to Processor A. Of those that are not assigned to Processor A, each of the remainder has a 33.3% (1-in-3) chance of being assigned to Processor B. Any transactions not assigned to Processor A or Processor B are assigned to Processor C.
