Orchestration activity designer

The Orchestration activity designer enables a user with either the workflow_admin or activity_creator and workflow_creator roles to construct reusable activities that suit an organization's business needs.

Activities created by the activity designer offer the following advantages over core activities offered in previous releases:

• Reuse custom activities in multiple workflows.
• Upload and download custom activities from the ServiceNow Store.
• Parse data from standard input formats.
• Test input variables against a target host or endpoint and inspect the payload.
• Automatically map values from a test payload to an activity's output variables.
• Share data between activities.
• View previous versions of an activity.

Access to the activity designer requires activation of ServiceNow Orchestration. For instructions about managing transitions and conditions for all activities, see .

Orchestration provides numerous pre-defined activities, which are reusable components that can be used in numerous workflows without having to understand the complexities of the underlying system. These activities are grouped into activity packs, which address specific business needs, such as: Active Directory, Azure AD, Exchange, Infoblox DDI, and PowerShell. There are other ServiceNow applications which provide and maintain their own separate activity packs, such as Security Incident Response, Cloud Management, or Release Automation.

Customers can also build their own activities and activity packs. You can construct custom activities with a specified template through the Orchestration Activity Designer. Custom-built activities built with the Activity Designer are referred to as activity elements. Activity elements provide optimal operations, enable code reuse, and minimize the need to write code. They also enable you to follow the flow of data within a given workflow across orchestration activities. Incorporating activity elements limits the dependency on the scratchpad which reduces problems in complex workflows. Limit the use of core activities, like ‘Run Script’, unless you need direct access the scratchpad, for example, for a counter. Activity elements do not have direct access to the scratchpad. You can, however, pass scratchpad variables as inputs into your activities.

Orchestration activities created by the activity designer:

• Can be uploaded and shared in the ServiceNow App Store
• Use the databus, which allows the activity to have well-defined inputs and outputs
• Share data across activities within a workflow
• Use versioning
• Provide a consistent approach for activity development regardless protocol

Note:

Prior to the Fujirelease, activities were built with Activity Definitions. In Fuji, a new architecture was introduced using the Activity Designer. Orchestration Core activities, built originally as Activity Definitions, have been converted to use the new template format (Activity Elements) and the databus offered with the activity designer. Workflows in upgraded instances that use legacy activities continue to work normally.

• Introduction to credentials, connections, and aliases for Orchestration
  All application integrations in Orchestration require connection information, credentials, and connection and credential aliases to their respective applications to access resources.
• Create custom activities using custom activity designer templates
  You can create and update different types of custom activities in the Workflow Editor using a custom template.
• Orchestration custom activity templates
  Orchestration provides customizable activity templates to create and manage custom activities in the Workflow Editor.
• Activity scoping
  Custom activities run in their own scope, even if it is different from that of the workflow.
• Publish a custom activity
  When a user creates a custom activity and saves or submits it, that activity appears in the Custom and Packs tabs of the designer palette, but is visible only to the user who created it.
• Copy a custom activity
  You can copy activities for reuse from the Custom tab in the global scope.
