### Request Body Object Example

```graphql
{
  "fields": {
    "name": "My Updated Shopping List",
    "primary": true
  },
  "mask": {
    "paths": [
      "name", "primary"
    ]
  }
}
```

The `fields` object allows you to specify new values for the shopping list attributes. Currently, we only support updating the `name` and `primary` attributes.

The `mask` object allows you to specify the attributes that you want to update specifically. For example, in each update request, you need to specify values for both `name` and `primary` attributes regardless of whether you want to update both or only one of them. Hence, the `mask` object determines which attributes are to be updated exactly.

The `mask` object contains the `path` array that allows you to add a comma-separated list of attributes to update.
