You will need the Full Write Workflows permission to perform this action. The permission must reach every campus of the workflow, and a workflow available to All can only be deleted by someone with no campus limit. Workflow managers cannot delete a workflow.
Click Automation > Workflows in the left navigation menu, then scroll or search for the workflow by name. On the Workflows listing, click the three-dot menu at the start of the row and select Delete.
You can also click the workflow's name and then click Actions > Delete.
A confirmation message appears. Enter the phrase shown and click Confirm Delete to finish.
Warning: All tasks in the workflow are deleted, and any linked forms or workflows become unlinked. Anyone currently in the workflow is removed. Their person profile is not deleted, and the history of what happened in the workflow stays on their profile.
