When the workflow trigger event occurs, the trigger checks that any required conditions are met, and if met, the "set-expiration" action sets a new expiration date. The due date is a period in the ISO 8601 format.
If adding the JSON trigger usingworkflow builder there is no need to include the opening "triggers": JSON markup notation, it is added automatically by workflow builder.
The "dueDate" period is set using ISO 8601 format. For example, "P6M3W5D" will be 6 months, 3 weeks, and 5 days from the date of transition into the state. This overrides any existing expiration periods.
An existing expiration period can be removed using the "clear-expiration" action.
