The checkout links are sorted by creation date, with the most recent appearing first. A **checkout link** is a unique URL sent to a pet parent (clinic client) that allows them to complete a purchase online. Each checkout link is associated with a specific clinic and client, and tracks whether the link has been opened and the communication method used to deliver it (e.g., SMS, email). ## OpenAPI ````yaml get /ext/v2/checkout-links/ openapi: 3.1.0 info: description: '' title: NinjaAPI version: 2.0.0 servers: - url: https://connect.vetcove.com/ security: [] paths: /ext/v2/checkout-links/: get: tags: - Checkout Links summary: List checkout links description: >- Returns a list of checkout links for a clinic.
