In the Configuration Tool, all aspects of the FastLink application, such as the product template (Aggregation, Verification, etc.), UI settings, region, and language preferences, can be set. Additional datasets (or data add-ons) that have to be aggregated, such as transactions, holder details, etc., are defined in the Set preferences section of the Configuration Tool.
Once you have created a new configuration template, be sure to set the styling rules or backend data settings and enter the mandatory Company Name. The configuration can be published to your development and production environments using the Save or Publish button.
