You can modify your vRealize Orchestrator workflows by adding actions scripts.
The vRealize Orchestrator Client provides libraries of predefined actions and an action editor for custom action scripts. Actions represent individual functions that you use as building blocks in workflows.
When a workflow runs, an action takes input parameters from the workflow's variables. These variables can be either the workflow's initial input parameters, or variables that other elements in the workflow set when they run.
The action editor includes an autocomplete feature for scripts and an API Explorer featuring the available scripting types and their documentation.
