Has a solution ever been provided? I too cannot create a metafield for a product using the admin api. I did the following:
URL: https://{API Key}:{Password}@{MyStore}.myshopify.com/admin/products/{product-id}/metafields.json
Action: Post
Body:
{
"metafield": {
"namespace": "global",
"key": "Test_Metafield",
"value": "Value for test metafield",
"value_type": "string",
"description": "This is the description"
}
}
When I try sending it I get a status 200 but with HTML as the response but no metafield was created for the product:
<html>
<body>
<noscript>
<a
</noscript>
<script type="text/javascript" defer>
window.location = "https:\/\/accounts.shopify.com\/oauth\/authorize?client_id=xxxxxxxxxxxxxxxxxxx\u0026destination_uuid=4xxxxxxxxxxxxxxxxxxxx\u0026nonce=xxxxxxxxxxxxxxxxxxx\u0026prompt=merge\u0026redirect_uri=https%3A%2F%2Fxxxxxxx.myshopify.com%2Fadmin%2Fauth%2Fidentity%2Fcallback\u0026response_type=code\u0026scope=email%20https%3A%2F%2Fapi.shopify.com%2Fauth%2Fdestinations.readonly%20openid%20profile%20https%3A%2F%2Fapi.shopify.com%2Fauth%2Fpartners.collaborator-relationships.readonly%20https%3A%2F%2Fapi.shopify.com%2Fauth%2Fbanking.manage\u0026state=xxxxxxxxxxxxxxxxx\u0026ui_locales=en\u0026ux=shop";
</script>
</body>
</html>
I even tried using basic authentication with the username set to my API key and the password with my API password and removed those values from the URL but I still get the same response in which no metafield gets created.
