Deletion has consequences for the resources inside a team or project and is not undone by creating another workspace with the same name. Do not assume that numbers, integration resources, or retained history can be restored.
Contact support as soon as you notice the mistake. Include what was deleted, the approximate time, your account email, and a support code if you still have it. Staff can investigate the state of the deletion request and explain what remains possible. Avoid repeating deletion or creating replacement resources while an uncertain operation is being investigated. Keep any exports you made before deletion.
