list.single_line_text_field Post?

[Chris_Sydney]

Hey There, 

Wondering if anyone has any guidance... I am sending the below payload to the following URL, but seem to be getting a bad request error. namespace and key are correct, as it the type.

https://{{store_name}}.myshopify.com/admin/api/{{api_version}}/variants/{{variant_id}}/metafields.json

{
        "metafield": {
            "namespace": "theme",
            "key": "highlight",
            "value": ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"],
            "type": "list.single_line_text_field"
        }
}

Hey @Chris_Sydney 

I think the payload has to include the variant ID, e.g.:

{"variant":
  {
    "id":808950810,
    "metafields": [
      {"key":"new","value":"newvalue", etc.. }
    ]
  }
}

Let me know if you get stuck!
