New release: Checkout Sessions API
Version 1.0.218The Checkout Sessions API creates a Wix‑hosted checkout session for a specific cart and buyer. Each call generates a fresh, single‑use session tailored to the provided line items and buyer details. You can use this API to create checkout sessions for one‑time or subscription line items, pre‑fill the checkout form with known buyer information to reduce friction at payment, and configure recurring billing per line item—including frequency, billing cycles, and free trial period (limited to one line item per checkout session).
