Add Product Variant - 404 Error

I am developing a VB.NET application to interact with our new Shopify store. I am in the process of automating product additions/updates/removal based on data in our Oracle database.

Basically the application creates a new Shopify part for a pattern, then creates product variants for each sku in that pattern. It does this by POSTing and PUTing requests using the

HttpWebRequest
class. This was working great through yesterday afternoon, now today for some reason it's failing on the product variant creation/update with a 404 - Not Found error code.

The product add request JSON is below. This works perfectly, it creates the part on Shopify which I can then see through the admin panel. This is POSTed to the URL "https://key:password@bath-and-window-direct.myshopify.com/admin/products.json" (where key and password are replaced with our credentials)

{
"product": {
"id": 0,
"body_html": "A classic combination of embroidery and cut work form the flowing border, creating your own seaside retreat. ",
"title": "Seabreeze Sand",
"vendor": "SKL",
"product_type": "",
"published_scope": "global",
"tags": "J71227",
"variants": null,
"options": null,
"images": [{
"id": 0,
"product_id": 0,

"src": "http:\/\/i320.photobucket.com\/albums\/nn353\/fkhphoto\/J71227main.jpg",
"variant_ids": null
}],
"image": null
}
}


This is the JSON reply I'm receiving after this call, and I can also see the part added in the Shopify admin panel:

{
"product": {
"id": 7874734983,

"variant_ids": []
}
}
}


Immediately after that, I'm POSTing the following JSON to add a product variant to this newly created part, to the URL "https://key:password@bath-and-window-direct.myshopify.com/admin/products/7874734983/variants.json". This is the call that returns a 404 - Not Found error through the
HttpWebRequest
class.

"key": "point5",
"value": " ",

}]
}
}


What am I doing wrong? The URLs, when copied into a web browser, work perfectly fine...I can see all the JSON of the current data. But when attempting to add the variant, I'm getting the 404.

Answer

Try leaving out the "id": 0 properties — both from the variant and from the metafields. Shopify will determine the IDs automatically.
