A workflow subscription is based on a specific topic schema. To ensure that the subscriptions initiate the vRealize Orchestrator workflows, you must configure them with the correct input parameters so that they work with the event data.

Workflow Input Parameters

Your custom workflow can include all the parameters or a single parameter that consumes all the data in the payload.

To use a single parameter, configure one parameter with a type of Properties and name inputProperties.

Workflow Output Parameters

Your custom workflow can include output parameters that are relevant to subsequent events necessary for a reply event topic type.

If an event topic expects a reply, the workflow output parameters must match the reply schema.
