External custom steps are available for Gateway cloud service and on-premises installations. You can add an external custom step in a flow to handle specific additional requirements to extend the capabilities of a standard flow provided in Gateway. External custom steps can be created and deployed outside of the Gateway server. The Gateway Customization SDK describes how to create and deploy an external custom step for Gateway.
