BigCommerce  allows business owners to set up an online store, customize it to their liking, and then sell an unlimited number of digital, physical, or even service-based products.

For adding products to the Bigcommerce cart we can use the following endpoint.

{{domain}}/cart.php

We have to add the following query parameters to the above endpoint.

Type	Parameter	Description	Example
string	action=	add or buy; buy goes directly to checkout add will add the product to cart	/cart.php?action=add&product_id=123
int	product_id=	product id to add to the cart	/cart.php?action=add&product_id=123
int	qty=	quantity to add to the cart	/cart.php?action=add&product_id=123&qty=3
string	sku=	SKU to add to the cart (or select on product page)	/cart.php?action=add&sku=xlredtshirt
string	couponcode=	coupon code to apply to the cart	/cart.php?action=add&product_id=123&couponcode=10off100

 

Example URL:

https://{{domain}}/cart.php?action=add&product_id={{id}}&qty={{qty}}

After adding the parameters just call the API and this will add the product to the bigcommerece cart!

Or

<a href=”https://example.com/cart.php?action=buy&product_id=123″>Purchase Our New Product Now!</a>

Purchase Our New Product Now!

The below sample JS code that can be used in Digioh Custom Js to add the products to Bigcommerce cart .

    return $.get("/cart.php?action=add&product_id=123")
  .done(function(data, status, xhr) {
    console.log('first item complete with status ' + status);
  })
  .then(function() {
    // add product id 456
    return $.get("/cart.php?action=add&product_id=456");
  })
  .done(function(data, status, xhr) {

  // chain more async GET requests using .then & .done
  .fail(function(xhr, status, error) {
    console.log('oh noes, error with status ' + status + ' and error: ');
    console.error(error);
