We hope to provide Workflow Validation, Condition and Post Function in the near future. In the meantime please use the following workarounds to add and delete using Jira Automation

Add Label Manager items through a workflow transition without overwriting existing label

Example Usecase:

When the status changes to “In Progress” add the Label “label1” in “red” to the Label Manager custom field “DoD”

Trigger: Issue Transitioned → Select From And/Or To Status

If: Check that the label is not yet selected.

Use “Advance compare Condition”

Use the Smart value {{<labelManagerFieldName>.labels}} and check ‘does not contain’ <labelName>

Edit Issue: New Action → Edit Issue

Use ‘More options’

Add the following code into the field. Replace ‘DoD’ with your Label Manager Field Name.

{
	"fields": {
		"DoD": {
                       "labels": [{{#DoD.labels}}"{{.}}",{{/}}"label1"],
                       "colors": [{{#DoD.colors}}"{{.}}",{{/}}"red"],
                       "labelSource": "{{DoD.labelSource}}"
		}
	}
}

Replace ‘label1’ with the color you want the new label to have.

Color options: ‘red’, ‘orange’, ‘green’, ‘grey-light’

If you want no color, you still need to add ‘grey-light’ here

Delete Label Manager items through a workflow transition

Example Usecase:

When the status changes to “In Progress” delete all labels selected in the Label Manager custom field “DoD”

Trigger: Issue Transitioned → Select From And/Or To Status

Edit Issue: New Action → Edit Issue

Use ‘More options’

Add the following code into the field. Replace ‘DoD’ with your Label Manager Field Name.

{
	"fields": {
		"DoD": {
                       "labels": [],
                       "colors": [],
                       "labelSource": "{{DoD.labelSource}}"
		}
	}
}
