Manage customer cart

Manage cart on customer’s behalf.

Ecwid.Cart.addProduct

This function allows to add a product to shopping cart, modifying the cart on behalf of customer.

There are 2 possible ways to call this function: adding products by product ID or adding products with extended options.

Adding by product ID

Add product function

Ecwid.Cart.addProduct(productID, callback);

addProduct() can accept 2 arguments: productId and callback.

NameTypeDescription
productIDintegerthe Ecwid’s internal product ID to be added to cart (can be retrieved from product export, seen in the URL of the product page or via REST API)
callbackfunctionthe callback function to be called once the operation is complete (either succeeded or failed). See below for details.

Add product to cart using ID

var productId = 10;
Ecwid.Cart.addProduct(productId);

The most simple call to Ecwid.Cart.addProduct only requires to pass the numeric product ID. See example code on the right. This code adds 1 item of the given product ID to cart.

If this product contains variations and the base product is out of stock, the first variation that is in stock will be added to cart instead. If the product is out of stock (and there are no variations in stock for this product), nothing is added to cart.

Adding with extended options

Add product to cart with extended options

var product = {
  id: 10,
  quantity: 3,
  options: {
    someTextOption: "Your name",
    someDateOption: new Date().getTime().toString(),
    someRadioOption: "Use default color",
    someDropDownOption: "I want custom engraving",
    someCheckboxOption: ["It's a gift", "Gold engraving"]
  },
  callback: function(success, product, cart) {
    // ...  
  }
}

Ecwid.Cart.addProduct(product);

If it is necessary to specify options or quantity of product to be added to cart, the product parameter needs to be passed as an object.

Since this method allows to specify the exact options to be added to cart, only the base product or variation matching those options will be added to cart. So, if the base product or matching variation is out of stock, the addProduct call will not add anything to cart, even if there are other variations in stock.

Callback

Adding to cart is done asynchronously, so if it is important to know the result of this function. The callback function can be passed as the second agrument of the function.

Add product to cart with callback function, example 1

Ecwid.Cart.addProduct(productID, function(success, product, cart){
  console.log(success); // true or false
  console.log(product.name);
});

Add product to cart with callback function, example 2

Ecwid.Cart.addProduct({
  id: 10, 
  quantity: 3, 
  callback: function(success, product, cart){
    console.log(success); // true or false
    console.log(product.name);
  }
});

Callback receives 3 arguments: success, product, cart

NameTypeDescription
successBooleanindicates the overall status of addition (succeeded or failed)
product<Product>conatins the object representation of the product added to cart, or null if adding to cart failed (wrong product ID or product is out of stock).
cart<Cart>contains the object representation of the shopping cart after addition (same as in Ecwid.OnCartChanged event)

Product

NameTypeDescription
idintegerProduct ID
quantityintegerAmount of products to add to cart
options<OptionsInfo>Selected product options for product
callbackfunctionFunction to run after the function is performed

OptionsInfo

NameTypeDescription
optionNamestring or array of stringReplace optionName with the real exact product option name you want to specify. Available values depend on the product option type: for checkbox options the value is array of strings, for all other options the value is a string

Ecwid.Cart.removeProduct

Remove specific product from cart

Ecwid.Cart.removeProduct(index);

Example

// returns cart details with items' details. Use 'items' array to get the index

Ecwid.Cart.get(function(cart){
  console.log(cart);
})

// remove first product from customer's cart

Ecwid.Cart.removeProduct(0);

Removes a product with specified index from customer’s cart. Ecwid.Cart.removeProduct() receives one argument: index

NameTypeDescription
indexintegerindex of a product in cart object you need to remove from customer’s cart

Ecwid.Cart.get

});

Ecwid.Cart.calculateTotal

Calculate cart total example

Ecwid.Cart.calculateTotal(function(order) {
  if (!order)
    alert('An error occurred while calculating the order!')
  else    
    alert('Order total: ' + order.total);    
});

Calculates the cart asynchronously and passes the result as an argument of type Order to the callback.

Cart calculation involves a request to server, so this method should be called only occasionally. Calling it frequently, e.g. from loops or by timer, is not acceptable.

Since the calculation needs a server connection, it might fail due to network conditions. In this case, null is passed into the callback instead of Order object.

Ecwid.Cart.gotoCheckout

Callback function after sending to checkout

  alert("Checkout process started");
});

You can also execute a callback function if a customer was successfully sent to the first step of the checkout process in a store. See example code on the right.

Generate cart with products

Ecwid JavaScript API allows you to add items to customer’s cart automatically. This can be useful when you are using custom storefront to provide any type of button to add products to cart.

Using the following steps you will be able to create links to your storefront with products in cart for your customers. So all they have to do is just clikc that promo link to go to your store and have products added to cart automatically.

Let’s check out how this can be achieved:

Step 1: Add external files to your website

Script and CSS to load on your storefront page

<link rel="stylesheet" type="text/css" href="https://d35z3p2poghz10.cloudfront.net/apps/ecwid-cart-app/cartapp.css">
<script src="https://d35z3p2poghz10.cloudfront.net/apps/ecwid-cart-app/1.0.0/cart.js"></script>

Add this code to the source code of the page, where your Ecwid storefront is displayed.

Step 2: Generate your cart

Generate items in cart example

var cartItems = [{
    "id": 66821181, // ID of the product in Ecwid
    "quantity": 3, // Quantity of products to add
    "options": { // Specify product options
        "Color": "White",
        "Size":"11oz"
    }
}, {
    "id": 66722581,
    "quantity": 5
}];

var cart = {
     "gotoCheckout": true, // go to next checkout step right away (after 'Cart' page)
     "products": cartItems, // products to add to cart
     "profile": {
         "address": { // Shipping address details
             "name": "john smith",
             "companyName": "general motors",
             "street": "5th Ave",
             "city": "New York",
             "countryCode": "US",
             "postalCode": "10002",
             "stateOrProvinceCode": "NY",
             "phone": "+1 234 235 22 12"
         },
         "billingAddress": { // Billing address details
             "countryCode": "US",
             "stateOrProvinceCode": "AL",
         },
         "email": "test@test.com", // Customer email
         "orderComments": "Comments!" // Order comments
     }
 }

cart = encodeURIComponent(btoa(encodeURIComponent(JSON.stringify(cart))));

console.log(cart);

// prints the resulting string you need to use in step 3
//

//

In order for the script to add items to cart, we need to 'tell’ it what items to add. Check the example on the right on how to do this. The cart variable will have the generated cart content in it.

The syntax is very similar to adding products to cart via Ecwid JavaScript API.

Step 3: Create a link for customers

Now we need to fill in customer’s cart when your custom link is opened.

First things first, let’s determine where your Ecwid store is displayed and get a direct link to that page. For example, our demo store is located in: https://www.ecwid.com/demo

And to fill in customer’s cart with items that you seleted earlier, we need to create a link to your storefront with the generated cart part.

Example link

Generated link with products added automatically to cart for Ecwid demo store will be:

Set order referrer

Set order referrer to 'Amazon’

ec.order = ec.order || {};
ec.order.referer_id = 'Amazon'

You can set a custom referrer for an order in storefront – use the ec.order.referrer_id field for your custom value.

Afterwards, this field will appear in order export via CSV, invoices and email notifications as a variable, and in the Ecwid REST API for orders.
