An API is not a database. It is an access point to an app that can access a database. In this post, we will focus on these specific kinds of APIs — web based APIs that return data in response to a request made by a client. They allow us to go get data from outside sources.

The API response is a status code 200, but the qty on the product does not change.



    request method: PUT
    json payload: [{"product_id":"395","inventory_level":55}]

     
    response status code: 200

You may remove items from your cart by clicking the "Shopping Cart" button, which is located just below the navigation menu. Click the selection box beside the item(s) you'd like to remove, and then click the "Remove Selected" button.
