Delete an existing budget. A deleted budget cannot be restored. The deleted budget is not available in the list of budgets.

Note:

• While you cannot restore a deleted budget with the API, you can unretire budgets in the BILL web app and mobile app. An unretired budget is active and is available for use.
• A one-time budget can be unretired at any time. A recurringInterval budget can be unretired within one interval. For example, if a MONTHLY budget is retired in January, you can unretire it in February. You cannot unretire this budget in March or any later month.
