addProductsToCart mutation
The addProductsToCart
mutation adds any type of product to the shopping cart. It streamlines the process of adding products by allowing you to specify multiple product types in a single call. We recommend using this mutation to add products to the cart instead of the single-purpose mutations, such as addSimpleProductsToCart
and addConfigurableProductsToCart
.
You must specify the Cart ID along with the list of SKU and quantity pairs as parameters to add the products to the shopping cart.
The CartItemInput
object now contains the selected_options
and entered_options
attributes. A selected option is predefined, and the shopper chooses from a set of possible values. Entered options generally contain text the shopper types, but other possibilities exist.
Selected options can be used in the following product types:
Customizable options such those presented in drop-down menu, radio buttons, and checkboxes
Bundle products
Configurable products
Downloadable products
Gift cards (amount)
Grouped products
Entered options can be used in the following product types:
Customizable options such as those presented in a text field, text area, or file
Gift cards (custom amounts, sender and recipient fields, messages)
Use the uid
attribute to reference selected or entered options. For entered options, the uid
represents an option value, while for entered options, the uid
represents an option. Each uid
is unique across different options in a set.

Add a configurable product to a cart
The following examples show two ways to add the same configurable product (WSH12
, a pair of shorts) to the cart.
Specify a parent and a child SKU

attribute, while the simple product variant is the sku
attribute.

Specify the SKU with selected options
In this example, the mutation specifies the size and color as selected options. The first option specifies the color, while the second option specifies the size. The products
query shows how to obtain the values specified in the selected_options
array.

Add a simple product with entered options
The following example adds a simple product with a customizable option to the cart. The customizable option allows the shopper to specify a message for engraving.
The customizable option is not part of the Luma sample data.
Request:
Copied to your clipboardmutation {addProductsToCart(cartId: "2m3Wpue1L3bNARhErAKbZ8Lb7czvgq6R"cartItems: [{quantity: 1sku: "24-WG03"entered_options: [{uid: "Y3VzdG9tLW9wdGlvbi8x"value: "Congrats, Julie!"}]}]) {cart {itemsV2 {items {product {namesku}... on SimpleCartItem {customizable_options {customizable_option_uidlabelvalues {customizable_option_value_uidvalue}}}quantity}total_countpage_info {page_sizecurrent_pagetotal_pages}}}user_errors {codemessage}}}

Add a bundle product with selected options to a cart
The following example adds the Sprite Yoga Companion Kit bundle product to the cart. The bundle product is comprised of four simple products, and the selected simple products are specified with a value in the selected_options
array. Use the products
query to determine these UID values. Note that each UID value is an encoded value representing the following string:
bundle/<bundle_option_id>/<bundle_option_selection_id>/<quantity>
Because the encoded value includes the quantity, the schema does not contain a quantity
attribute for individual simple products.
In this example, the UID values are encoded versions of these strings:
Copied to your clipboardbundle/1/1/1bundle/2/4/1bundle/3/5/1bundle/4/8/1
Request:

Add a bundle product with entered options to the cart
For entered_options
, the uid
attribute contains the encoded entered value. The value
attribute defines the quantity. If the BundleProduct.items.options.can_change_quantity
attribute is false
, then the bundle product definition sets the quantity for the simple product. Otherwise, the shopper decides the quantity.
The Luma sample data does not provide any bundle products with entered options. The following snippet shows how to construct the mutation.
Copied to your clipboardmutation {addProductsToCart(cartId: "ELwvX8VJinGJ9Q2vOXSiCTS4gvCDKP8U"cartItems: [{quantity: 1sku: "bundle1"entered_options: [{uid: "EncodedEnteredValue1"value: 1}]selected_options: ["EncodedSelectedValue1""EncodedSelectedValue2"]}]) {cart {itemsV2 {items {uidproduct {namesku}quantity... on BundleCartItem {bundle_options {uidlabeltypevalues {idlabelpricequantity}}}}total_countpage_info {page_sizecurrent_pagetotal_pages}}}user_errors {codemessage}}}
