The following questions walk you through some of the things you need to consider when
setting up routing.
Step Question Yes No
Identify each payment instrument Proceed to step 3.
BASE24-eps will need to recognize for the card issuer.
If you plan to authorize transactions on the system, identify the PAN lengths and prefixes that will be used with each payment instrument.
Do you plan to authorize
transactions for card issuers on the system or route transactions for card issuers to a host?
1
Identify the authorization scripts you want to use for authorizing the transactions for the card issuer.
Set up a prefix record for each prefix and PAN length combination to be used to identify each payment instrument, specifying in each prefix record a destination route profile and route type that will direct the transactions to the appropriate authorization script or host interface.
Proceed to step 2.
No sequential routing is needed.
Proceed to step 3.
Identify and modify the necessary scripts to include sequential routing.
Use these modified scripts as destinations in your destination routing profiles.
Do you want to involve multiple external entities in authorizing transactions for your card issuers (i.e., do you want to perform sequential routing )?

Note: Modifying scripts to include sequential routing takes
considerable planning and testing.

profile and assign it to all of your terminals.
Create a single destination routing profile and use it for all transaction routing from your terminals.
Are all transactions from all of your terminals to be routed the same way?

Step Question Yes No No business relationship table needs to be set up for your terminals.
No routing codes need to be set up.
Create a source routing profile for each group of terminals to be associated with a specific acquirer and assign the profile to each terminal in the group.
Create a separate destination route profile for any issuer to be included in a business relationship.
Do you want any groups of terminals to be associated with specific acquirers so that a business relationship with an issuer can be taken into account during routing?
3b
Specify only default routing codes of all asterisks in your destination routing profile.
Create a business relationship table to associate the source routing profiles assigned to your terminals with the destination routing profiles created for your issuers.
Proceed to step 3c.
Identify the transaction types that can be accepted from these terminals and tie them to route codes in your business relationship table.
Include route codes in your separate destination routing profiles.
Proceed to step 3c.
Create a source routing profile for Proceed to step 4.

Create a separate destination route profile for each group of terminals to be routed the same.
Do you want certain groups of terminals to be routed differently from others (aside from any involved in possible business relationships)?

Are the interchange transactions identifiable using an algorithm?

Return to step 4, and verify that you know how you will route outbound interchange transactions.

Create a single destination routing profile and use it for all transaction routing.
Are all transactions from all your interchanges to be routed the same way?

No routing codes need to be set up for the interchanges. Specify only default routing codes of all asterisks in your destination routing profile
Create a source routing profile for each interchange to be associated with a specific acquirer and assign the profile to each interchange interface.
Create a separate destination route profile for any issuer to be included in a business relationship.
