### Vendor notifications

The vendor webhook notifications now include the `shortName` field. This field is the vendor short name. When you receive notifications for the `vendor.created`, `vendor.updated`, `vendor.archived`, or `vendor.restored` events, the notifications now include the `shortName` field.

### Bill notifications

The bill webhook notifications now include the `purchaseOrderNumber` field. This field is the purchase order number linked with the bill. When you receive notifications for the `bill.created`, `bill.updated`, `bill.archived`, or `bill.restored` events, the notifications now include the `purchaseOrderNumber` field.
