Update product metafield with metaobject entry through Shopify flow

Shopify Plus
11

That is a list of metaobjects. So it’s like [“gid://shopify/Metaobject/123”,“gid://shopify/Metaobject/123”]

Probably what you actually need to do then is update a Metaobject. To do that you would need to call MetaobjectUpsert via Send Admin API request. Here’s an example request that works:

{
  "handle": {
    "type": "recipe",
    "handle": "scrambled-eggs"
  },
  "metaobject": {
    "handle": "scrambled-eggs",
    "fields": [
      {
        "key": "ingredients",
        "value": "[\"eggs\",\"milk\",\"foo\"]"
      }
    ]
  }
}
