Bulk Add Items to Cart
With the bulk add feature, a shopper can add an array of items to their cart in one action, rather than adding each item one at a time. Shoppers can specify items by selecting one of the two options, by SKU or by product ID. This minimizes the time a shopper spends adding items to a cart. An example for bulk add is:
{
"data": [
{
"type": "cart_item",
"sku": "sku-1",
"quantity": 1
},
{
"type": "cart_item",
"sku": "sku-2",
"quantity": 1
}
],
"options": {
"add_all_or_nothing": true
}
}
With the bulk add items to cart capability you can use one or more of the following cart actions in a transaction:
important
The request body depends on the type of items that you want to add, such as promotion, custom or product.
Dynamic Bundles
A bundle is a purchasable product that is composed of a combination of two or more products that you want to sell together. You can create multiple components within a bundle. Each component can have one or more options. Each option is a product and a quantity. You can configure minimum and/or maximum values for the number of product options in a component that your shoppers can select. For example, you can enable a shopper to select 1 or more product options from a list of 10. These are called dynamic bundles.
Your dynamic bundles are displayed in your published catalogs. Shoppers make their selections. A shoppers selections are stored in the configure a shopper bundle endpoint. The shoppers selections are stored in a bundle_configuration which is supplied in the add product to cart request.
"bundle_configuration": {
"selected_options": {
"games": {
"d7b79eb8-19d8-45ea-86ed-2324a604dd9c": 1
},
"toys": {
"0192ccdd-6d33-4898-87d7-c4d87f2bf8ea": 1,
"1aea6f97-f0d9-452c-b3c1-7fb5629ead82": 1
}
}
}
When a cart is checked out, the options a shopper selected are added to the order. See order items.
Personalized Products
You can allow your shoppers to add custom text to a product when adding product items to their carts. This is useful, for example, if you have a product like a T-shirt that can be personalized. You can do this using the custom_inputs attribute. The custom_inputs attribute must be an object. For example, you sell greetings cards that can be printed with your shoppers personalized messages.
Once you have defined your custom inputs on a product, you must configure the custom inputs in your orders.
For example, a birthday card may have custom inputs for name and message defined for a product.
{
"custom_inputs": {
"name": {
"name": "Name",
"validation_rules": {
"type": "string"
},
"message": {
"name": "Message",
"validation_rules": {
"type": "string"
}
}
}
}
}
When the product is added to the cart, those custom inputs are supplied.
{
"custom_inputs": {
"name": {
"name": "Fred",
"message": "Happy Birthday"
}
}
}
If the same product has different custom_inputs attributes, then these are added as separate items in a cart.
The custom_inputs attribute is stored in the cart item and must not exceed 1MB. When a cart is checked out, the custom_inputs attribute becomes part of the order items.
When you add products to a cart with custom_inputs, there are certain limitations on usage of the custom_inputs with the following promotion types:
- For Free Gift Promotions, you can add
custom_inputsto gift items. - For Fixed Bundle Discount Promotions, the promotion applies as long as the cart contains the bundle SKUs even when there are different
custom_inputs. - For X for Y Discount Promotion and X for amount discount promotion, the promotion applies when there are two SKUs with the same
custom_inputs. The promotion does not apply when there are differentcustom_inputsand the SKUs are in different line items.
