Processor configurations

Boarding requires a processor_config_id available to your account in the same environment. List available configurations before choosing an ID.

Configuration	UAT `processor_config_id`	Production `processor_config_id`
Fiserv Nashville North (equipment-based)	Not listed	Not listed

If an ID is not listed, contact support@koard.com for the appropriate configuration.

Examples without a listed UAT ID are request templates. Replace YOUR_PROCESSOR_CONFIG_ID with an available configuration ID before submitting a request.

Use this format for a Nashville North configuration assigned to your merchant. See the Fiserv overview for common fields.

This page covers the equipment-based request format. For a configuration that requires the business name and merchant address without equipment fields, use the address-based Nashville North example.
