# Update Line Item

PUT https://your_store.example.com/api/storefront/checkouts/{checkoutId}/carts/{cartId}/items/{itemId}
Content-Type: application/json

Updates a *Checkout Line Item*. Updates an existing, single line item in the cart.

If a variant needs to be changed or updated, the product will need to be removed and re-added to the cart with the correct variants using the [Add Cart Line Items](/developer/api-reference/rest/storefront/carts/cart-items/add-cart-line-item) endpoint or the [GraphQL Storefront API](/developer/docs/storefront/guides/graphql-storefront-api/overview).

> #### Notes
> * Substitute your storefront domain for `yourstore.example.com`. 
> * The Send a Test Request feature is not currently supported for this endpoint.  
> * Please note that this API endpoint is not concurrent safe, meaning multiple simultaneous requests could result in unexpected and inconsistent results.
> * This endpoint runs in the context of an active storefront session and works on any live BigCommerce-hosted storefront, not only in a local environment. It uses [same-origin CORS authentication](/developer/docs/overview/api-fundamentals/api-accounts#same-origin-cors-authentication), and write requests require a CSRF token. Stencil CLI can provide a session and CSRF token for local theme development.
