A workflow subscription is based on a specific topic schema. To ensure that the subscriptions can start the vRealize Orchestrator workflows, you must configure them with the correct input parameters so that they work with the event data.
Workflow Input Parameters
The custom workflow that you create can include all the parameters or a single parameter that consumes all the data in the payload.
To include individual parameters, configure one or more parameters. Ensure that the name and type match the name and type specified in the schema.
To use a single parameter, configure one parameter with a type of Properties. You can provide any useful name. For example, you can use payload as the parameter name.
Workflow Output Parameters
The custom workflow that you create 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.
