# Services without Conversion Rules

Substation ES services can handle communications without the requirement for conversion rules. When this method is used, Substation ES services do not require the definition of conversion rules to communicate with CICS applications or create ESB messages.

Single or multiple containers in CICS can be used for automated interactions. You can follow a few easy configuration steps to implement this flawlessly and efficiently.

See Recipe Service and Trigger Service for their respective implementations.
