Get InventoryItem ID from Product

[DoubleShot]

Currently I create a new Product with the REST API, and then I make a GraphQL inventoryItemUpdate to change the HS code. However, I need the InventoryItem ID to do this, not the Product ID. How do I get that? Here's my Product creation:

[
    {
        "title": "Test Product",
        "status": "draft",
        "variants": [
            {
                "sku": "testing-sku-234n6j",
                "price": 0,
                "inventory_quantity": 1,
                "inventory_management": "shopify"
            }
        ],
        "body_html": "Test Description",
        "published": true,
        "published_scope": "global"
    }
]

Hi, there 

You need to utilize your product ID to obtain its related product variants, and each product variant has a one-to-one mapping to an InventoryItem.

What API endpoint can I use to do that?

Hi @DoubleShot 

We need to modify your parameter structure. The following are the modified parameters and the return result, which includes variant data information

{
    "product": {
        "title": "Test Product",
        "status": "draft",
        "variants": [
            {
                "sku": "testing-sku-234n6j",
                "price": 0,
                "inventory_quantity": 1,
                "inventory_management": "shopify"
            }
        ],
        "body_html": "Test Description",
        "published": true,
        "published_scope": "global"
    }
}

Response data:

I forgot to look under the variants of the return data, thanks for the helpful reply!
