Note

Medium Risk
Changes the Link card authorize contract and payment amount limits; integrators must pass checkout browser context for Pay Token flows and handle new immutability rules after authorization.

Overview
Release 0.126.0 updates the Node SDK for checkout-aware Link card authorization, including support for Link Pay Tokens when the merchant checkout allows it.

performOperation with type: 'authorize' now accepts optional browser_id and page_url on Link cards. With both set on the final checkout page, Kernel inspects the checkout and picks a merchant-bound Link Pay Token or a virtual card; omitting them still issues a merchant-origin virtual card. Types and JSDoc describe updated Link amount caps (higher for Pay Token vs virtual card), that authorized Link cards bound to checkout context cannot be PATCHed (delete and recreate instead), and that fill may omit fields when the item’s advertised operation does not require bindings. Vault wallet items also gain an optional server description field for agent guidance.

Version metadata (package.json, CHANGELOG, release manifest) is bumped to 0.126.0; a skipped vault items test reflects the new authorize parameters.
