API Create Product {"errors":{"product":"Required parameter missing or invalid"}}

Shopify Apps

Topic summary

Issue: Creating a product via the Shopify Admin API (2024-07) succeeds on one store but fails on another with HTTP 400 and error: {“errors”:{“product”:“Required parameter missing or invalid”}}.

Request details: POST [store]/admin/api/2024-07/products.json with a product payload including title, product_type, status: “active”, published_scope: “global”, published: true, empty metafields, images, and one variant (inventory_management: “shopify”, inventory_policy: “continue”, presentment_prices, etc.). A code snippet is central to understanding the request.

Discussion: One reply suggested the image URL is incomplete (“images”:[{“src”:“https:”}]). The author tested three variants: removing the images field, removing just “https:”, and providing a full URL. All attempts still return the same 400 error.

Current status: Root cause remains unknown; the error message does not indicate which parameter is invalid or missing. No resolution yet; the thread is open with an outstanding question about which field is causing validation to fail.

Hello,

I’m trying to create products on stores using the shopify API.

It’s working fine on one store but not in the other.

Here is the request :

POST : [store_url]/admin/api/2024-07/products.json
Content-type : application/json

Body

{
    "product": {
        "title": "TEST SHOPIFY - NE PAS EFFACER",
        "body_html": "",
        "vendor": "SHOPIFY",
        "product_type": "Antivol à code",
        "status": "active",
		"published_scope": "global",
		"published": true,
		"metafields": [],
"images":[{"src":"https:"}],
        "variants": [
            {
                "title": "Default Title",
                "price": "20",
                "sku": "",
                "position": 1,
                "inventory_policy": "continue",
                "fulfillment_service": "manual",
                "inventory_management": "shopify",
                "option1": "Default Title",
"metafields": [],
                "option2": null,
                "option3": null,
                "taxable": true,
                "barcode": "",
                "weight": 2,
                "inventory_quantity": 1,
                "old_inventory_quantity": 0,			
                "presentment_prices": [
                    {
                        "price": {
                            "amount": "20",
                            "currency_code": "EUR"
                        },
                        "compare_at_price": null
                    }
                ],
                "requires_shipping": true
            }
        ]
    }
}

On one store the product is successfully created.
On the other a status code 400 with the error message

{"errors":{"product":"Required parameter missing or invalid"}}

The error message does not tel me what parameter is missing.

Hello, the image url in your request seems to be incomplete. Could that be the issue?

Hey @gojiberry-des

Thanks for the reply,
I tried :

  • removing the
"images":[{"src":"https:"}],
  • Removing https:
  • Adding a complete url

Still getting the error 400.
