Car Wash Working Group

Mission Statement: To create an FDC-Car Wash standard that can be leveraged for modern car wash functionality and by devices on the forecourt with similar use cases (e.g., air pumps).

Active Projects: 

This Working Group is under the Device Integration Committee.  A standard interface will allow car wash manufacturers and forecourt device controller manufacturers to achieve greater interoperability among car wash and site system vendors.  This result will facilitate the introduction of new functionality surrounding car wash.  This interface may also be utilized for other similar forecourt devices, such as vacuums and air pumps.

The development of a car wash interface will provide for a common protocol for a car wash device to communicate to other site systems.  This first version of the Car Wash Specification standardizes generating API car wash codes.  Version 1.0 was published in September 2021. Future versions will fulfill these requirements:

  • Selling a car wash from an external device (e.g., dispenser, POS);
  • Payment processing;
  • Reconciliation and reporting of car wash information;
  • Alerts; and
  • Price management.

Goals for 2021:

  • Q1:  CW API Reporting and Transaction Reconciliation
  • Q2:  Work on APIs documentation 
    • CW API Demonstration at the Conexxus Annual Conference May 1-5

  • Q3:  CW API Alerts
  • Q4:  CW API Price Management


The Working Group Chair is Richard Carpenter, DRB In-Bay Solutions.

The Working Group Vice-Chair is Thomas Bagnara, ICS.
