Adding new orderlines to cart using dwapi

Hello,

Dynamicweb 9.15.3

We are adding products to a cart using the following dwapi endpoint - (POST)/dwapi/ecommerce/carts/{secret}/items

When we add a product that already exists in Cart, instead of incrementing the existing orderline quantity, a new orderline is being added. Is this the expected behaviour? should we validate first if product is in cart and use a different endpoint?

Example request body we are submitting to the API

Yes, that is expected behavior.

POST means create new - if you want to update an existing one, use PATCH endpoint.

PATCH /dwapi/ecommerce/carts/{secret}/items/{itemId}

I am not sure how you do the implementation, but usually you would have a cart object in JS with the cartlines and make the decission there.

We could add a "CreateOrUpdate" endpoint or add a parameter to the POST endpoint so it can merge if product is the same.

Hi Nicolai,

Thank you for the explanation. We are trying to do a bulk import for one of our customers.

1 - User uploads an excel file
2 - We validate if the products exist or are out of stock

3 - Add valid products to cart

If you can make it have a similar behavior as when we add a product to cart in frontend (if the product is already there - merge), that would help us a lot.

Thank you.
