# Cart change REST API now supports changing selling plan

It’s now possible to upsell subscriptions in cart in the online store. We added a new field, `selling_plan`, to the [`/cart/change.js`](https://shopify.dev/api/ajax/reference/cart#post-cart-change-js) endpoint in the AJAX REST API to support adding, updating, and removing the selling plan.
