# Renames the date field for invoices to created ## What’s new Renames the `date` property for invoices to `created`. ## Impact This change renames the `date` property to `created` for `Invoice` objects. You need to update your code to reference `created` instead of `date` when accessing the creation timestamp of an invoice. This modification aligns the invoice property naming with other objects in the API. ## Upgrade #### REST API 1.
