When I Work Annotations API
Annotations convey important information to all staff for the given schedules (locations) and date range. Any or none of the following tags may apply to an Annotation: * Time Off Not Allowed * Business Closed * Announcement The "Time Off Not Allowed" tag is the only tag that affects the behavior of another API. Time Off requests will be considered invalid if the request's date range overlaps an Annotation of the "Time Off Not Allowed" type for the user's location(s).
