Deprecation Notice:
The eCommerce Checkout API has been replaced with Cart V2 and will be removed on February 1, 2027. Cart V2 unifies cart and checkout into a single Cart entity, so there's no separate checkout step.
For migration guidance, see the Cart V2 Migration Guide.
The checkout is the second stage of the eCommerce purchase flow: cart; checkout; order.
A checkout holds information about items to be purchased, price and tax summaries, shipping and billing info, any applied discounts, and more.
The eCommerce Checkout API currently provides functionality for retrieving checkouts and listening to events when a checkout is created, updated, and marked as completed.
