You can design blueprints to run any of the available workflows. For example, you can design blueprints to create or delete OpenStack projects, and to deploy or delete Heat stacks.
Service Accounts for vRealize Orchestrator Workflows
You can use service accounts for authentication when you design blueprints. These accounts are used by default for authentication of the OpenStack REST API and users do not have to enter credentials every time they request services. When you use service accounts, set the credentials related parameters as not visible to the users. You create these accounts as standard OpenStack users.
