The items are sorted by creation date, with the most recent appearing first. When using modified filters, results are sorted by modification date instead. An invoice item represents a single line item on a clinic invoice — a service rendered, product dispensed, or other billable charge. Each item tracks the quantity, unit price, applicable discounts and taxes, and the resulting total. Each item is associated with a specific patient. ## OpenAPI ````yaml get /ext/v2/invoice-items/ openapi: 3.1.0 info: description: '' title: NinjaAPI version: 2.0.0 servers: - url: https://connect.vetcove.com/ security: [] paths: /ext/v2/invoice-items/: get: tags: - Invoices summary: List all invoice items description: >- Returns a list of all invoice items across all clinics in the organization.
