Action Name:

  • The action name should describe what the action is doing from a business perspective.
  • The name is used as the name of the result object returned by the action (JSON) so it is important to set this early before the action results are used.
  • Once the actions results are referenced by dynamic content the “rename” option will be disabled and the name cannot be changed
