How to Add Products to Cart & Quote in Magento 2

Magento 2 comes with four default types of products:

  • Simple product
  • Downloadable product
  • Configurable product
  • Bundle product

In this article, I will instruct you to add four types of products (including a simple product, a downloadable product, configurable product, and a bundle product) to the cart. On behalf of a customer, all calls are performed, and the customer’s token is specified in the authorization header. Let’s explore the process together!

How To Add A Simple Product To A Cart

To add a simple product to a cart, you are required to specify a SKU, the quantity, and the quote ID, which was generated when the cart was created.

In this post, we take an example of adding an orange medium-sized Radiant women’s t-shirt (SKU: WS12-M-Orange) to the cart.

Endpoint

POST <host>/rest/<store_code>/V1/carts/mine/items

Headers

Content-Type application/json

Authorization Bearer <customer token>

Payload

{
  "cartItem": {
    "sku": "WS12-M-Orange",
    "qty": 1,
    "quote_id": "4"
  }
}

Response

{
  "item_id": 7,
  "sku": "WS12-M-Orange",
  "qty": 1,
  "name": "Radiant Tee-M-Orange",
  "product_type": "simple",
  "quote_id": "4"
}

How To Add A Downloadable Product To A Cart

To add a downloadable product to a cart, you muust provide the SKU, the quantity, and quote ID.

In our example, we will add the downloadable product Advanced Pilates and Yoga (SKU: 240-LV08).

Endpoint

POST <host>/rest/<store_code>/V1/carts/mine/items

Headers

Content-Type application/json

Authorization Bearer <customer token>

Payload

{
  "cartItem": {
    "sku": "240-LV08",
    "qty": 1,
    "quote_id": "4"
  }
}

Response

{
  "item_id": 8,
  "sku": "240-LV08",
  "qty": 1,
  "name": "Advanced Pilates & Yoga (Strength)",
  "price": 18,
  "product_type": "downloadable",
  "quote_id": "4",
  "product_option": {
    "extension_attributes": {
      "downloadable_option": {
        "downloadable_links": [
          5
        ]
      }
    }
  }
}

How To Add A Configurable Product To A Cart

To add a configurable product to a cart, you need to provide the SKU as well as the set of option_id/option_value pairs which make the product configurable.

The following example, add the Chaz Kangeroo Hoodie (SKU: mh01) configurable product to the cart. This product offers three colors (black, gray, and orange) and fives sizes (XS, S, M. L. XL). In the sample data, the option_id values for Size and Color are 141 and 93, respectively. To get the option_id values for the given SKU, you can use the GET /V1/configurable-products/:sku/options/all.

The returned values of the GET /V1/configurable-products/:sku/children call is each combination of color and size, 15 in all for MH01. The below sample displays the returned values for size and color attribute of a small gray Chaz Kangeroo Hoodie.

{
  "custom_attributes": [
    {
      "attribute_code": "size",
      "value": "168"
    },
    {
      "attribute_code": "color",
      "value": "52"
    }
  ]
}

Now you know the values for option_value for size and color are 168 and 52, so it is time for you to add product to the cart.

Endpoint

POST <host>/rest/<store_code>/V1/carts/mine/items

Headers

Content-Type application/json Authorization Bearer <customer token>

Payload

{
  "cartItem": {
    "sku": "MH01",
    "qty": 1,
    "quote_id": "4",
    "product_option": {
      "extension_attributes": {
        "configurable_item_options": [
          {
            "option_id": "93",
            "option_value": 52
          },
          {
            "option_id": "141",
            "option_value": 168
          }
        ]
      }
    },
    "extension_attributes": {}
  }
}

Response

{
    "item_id": 13,
    "sku": "MH01-S-Gray",
    "qty": 1,
    "name": "Chaz Kangeroo Hoodie",
    "price": 52,
    "product_type": "configurable",
    "quote_id": "4",
    "product_option": {
        "extension_attributes": {
            "configurable_item_options": [
                {
                    "option_id": "93",
                    "option_value": 52
                },
                {
                    "option_id": "141",
                    "option_value": 168
                }
            ]
        }
    }
}

How To Add A Bundle Product To A Cart

The Sprite Yoga Companion Kit (SKU: 24-WG080) is a bundle product which is provided by the sample data. There are many items included in the kit, as follows:

  • Sprite Statis Ball in sizes 55 cm (SKU: 24-WG081-blue), 65 cm (SKU: 24-WG082-blue), or 75 cm (SKU: 24-WG083-blue)
  • Sprite Foam Yoga brick (SKU: 24-WG084)
  • Sprite Yoga Strap in lengths 6 ft (SKU: 24-WG085), 8 ft (SKU: 24-WG086), or 10 ft (SKU: 24-WG087)
  • Sprite Foam Roller (SKU: 24-WG088)

The requirement for adding a bundle product to a cart is specifying the SKU of this bundle product, but not the individual items. To add individual items to the bundle product, you need to specify the ID defined in the item’s product_links object. The primary function of the product_links object is describing the ordering and placement of options on the customization page. Besides, it links an item’s SKU and ID to the SKU of the bundle product.

The returns of the GET <host>/rest/<store_code>/V1/bundle-products/24-WG080/options/all call are id values, as displayed in the below simplied response:

[
  {
    "option_id": 1,
    "title": "Sprite Stasis Ball",
    "required": true,
    "type": "radio",
    "position": 1,
    "sku": "24-WG080",
    "product_links": [
      {
        "id": "1",
        "sku": "24-WG081-blue",
        "option_id": 1,
        "qty": 1
      },
      {
        "id": "2",
        "sku": "24-WG082-blue",
        "option_id": 1,
        "qty": 1
      },
      {
        "id": "3",
        "sku": "24-WG083-blue",
        "option_id": 1,
        "qty": 1
      }
    ]
  },
  {
    "option_id": 2,
    "title": "Sprite Foam Yoga Brick",
    "required": true,
    "type": "radio",
    "position": 2,
    "sku": "24-WG080",
    "product_links": [
      {
        "id": "4",
        "sku": "24-WG084",
        "option_id": 2,
        "qty": 1
      }
    ]
  },
  {
    "option_id": 3,
    "title": "Sprite Yoga Strap",
    "required": true,
    "type": "radio",
    "position": 3,
    "sku": "24-WG080",
    "product_links": [
      {
        "id": "5",
        "sku": "24-WG085",
        "option_id": 3,
        "qty": 1
      },
      {
        "id": "6",
        "sku": "24-WG086",
        "option_id": 3,
        "qty": 1
      },
      {
        "id": "7",
        "sku": "24-WG087",
        "option_id": 3,
        "qty": 1
      }
    ]
  },
  {
    "option_id": 4,
    "title": "Sprite Foam Roller",
    "required": true,
    "type": "radio",
    "position": 4,
    "sku": "24-WG080",
    "product_links": [
      {
        "id": "8",
        "sku": "24-WG088",
        "option_id": 4,
        "qty": 1
      }
    ]
  }
]

In this example, we will configure the Sprite Yoga Companion Kit as follows:

  • 65 cm Sprite Stasis Ball (id: 2)
  • Sprite Foam Yoga Brick (id: 4)
  • 8 ft Sprite Yoga strap (id: 6)
  • Sprite Foam Roller (id: 8)
