Shopping List

The Shopping List API service offers you the ability to read and write your shopping list data.

Let's first understand the Shopping List object and its data structure before looking at its endpoints’ description.

Shopping List Object

A Shopping List object is a collection of arrays and child-objects that defines its data structure. This is how the data structure of a shopping list looks in JSON format:

{
  "list": {
    "id": "106f9105f1d05d24ad2b833f5d2a966be77",
    "name": "My Shopping List"
