Getting current Cart Id in Bigcommerce - bigcommerce

Question

So, I am using the cart API of Bigcommerce for adding items to the cart from a different domain which is working fine. However, when I try to repeat adding other items to the same cart it does not work. So, is there a way I can get the cart ID for an instance so that I can update my items to the existing cart?

Answer 1

The Storefront API allows you to retrieve the current cart.
Execute this in the javascript console after adding an item to cart
fetch('/api/storefront/carts?include=',
{
'credentials':'include',
'headers':{
'Accept':'application/json',
'Content-Type': 'application/json'
}
}).then(function(response){
response.json().then(function(data) {
console.log(JSON.stringify(data, null, 3))
})
});
returns something like this
[
{
"id": "aaaaaaaa-bbbb-ccccc-dddd-eeeeeeeeeeee",
"customerId": 0,
"email": null,
"currency": {
"name": "US Dollars",
"code": "USD",

Answer 2

When you created your first item, the response will include Cart ID. Use this Cart ID to add more items to the same cart.
