Create order via API - Could not add product to cart

SethSeth Member Posts: 5

We try to create an order via the API for It is for product with variantid: 105889589. The API responses with: “Could not add product to cart”.

Usually this means that the product (or variant) is out of stock, and thus not orderable via the frontend of the webshop.

However, we are able to order this product (variant L) via the frontend:

Our call:

Did we overlook something?

    Hi @Seth,


    Sorry for the delay in answering your question.

    What I can see is that you are making use of a required custom field. I've tested this in my own environment and was getting the same result. What you can do is to add the custom field to the checkout:

    I hope this will help to solve this issue.

    Kind Regard,

    Hi guys,

    I'm new to Lightspeed and trying to understand the API.

    I want to create a configurator app that can in the end add a product to a cart and jump to the website to do the checkout via the site. I can read products from the API, but how would I add a products to a cart and then finish that flow on the website?

    Should this be done through the api? or a post to the website? We have this url on the website /cart/add/{variant_id}/ but them I'm supposed to supply those custom fields, but I don't know how..
