I am using Magento 2 default quoteCartItem restful APIs to add, delete and update items in cart. Things are working as expected.

GET /V1/carts/{cartId}/items
POST /V1/carts/{cartId}/items
DELETE /V1/carts/{cartId}/items/{itemId}
PUT /V1/carts/{cartId}/items/{itemId}
GET /V1/carts/mine/items
POST /V1/carts/mine/items
DELETE /V1/carts/mine/items/{itemId}

Now, I have to add an identifier/flag to identify whether the user has chosen the item as home delivery or self pick-up.

  • What are the quote item options and when we need it?
  • How to add custom attribute/option to quote item?
  • Is there any in-built API, which I can use achieve my requirement?
  • Do I need to write Custom API for this?

I'm new in magento 2, not too familiar with technical keywords. Hope I explained this question properly.

  • So you just want to choose the shipping methods for your cart ? Commented Sep 7, 2016 at 9:51
  • Customer can make one or multiple item from cart as home delivery and rest as self pick-up Commented Sep 7, 2016 at 10:35

I have working with magento2 API and below ans could be something useful for you.

Step1: First of all you need to generate an empty cart for customer. If customer is already registered then you need to pass customer_id as an parameter like below.

Request URL: http://magentohost/rest/V1/carts/mine
parameters: {"customer_id":"7"} //your customer_id goes here.
Response: "9" is quote id. // This will return Quote Id.

It will return quote id as a response.

Step2: For adding a product to cart with custom options you need to call below url

Request URL: http://magentohost/rest/V1/carts/mine/items

parameters: {
    "cart_item": {
        "quote_id": "9",
        "sku": "24-MB01",
        "qty": 1,


  "item_id": 9,
  "sku": "24-MB01",
  "qty": 1,
  "name": "Joust Duffle Bag",
  "product_type": "simple",
  "quote_id": "9",
  "product_option": {
    "extension_attributes": {
      "custom_options": [
          "option_id": "1",
          "option_value": "2"

Refer Link: https://github.com/magento/magento2/issues/4381 .

I have tested it with postman which gives me cart with added custom option in it. Magento provides default API to add custom options in cart so there wont be need to add custom API for the same.
Also here is link which would be helpful for the same.


  • Thanks for your ans but its not very much close to my requirement. I have to add an identifier/flag to identify whether the item in the cart is a home delivery or self pick-up. Commented Sep 13, 2016 at 7:26
