Can't update Metadata with API

[Keo 3]

Can someone tell me what I am doing wrong here?  I am trying to update movie metadata using the ItemUpdateService API.  When ever I execute this in swagger I get the following error:

Value cannot be null.
Parameter name: source

I've looked over all of the fields and the examples supplied in swagger, but I do not see a source parameter.  Can someone explain to me what I am doing wrong?

Can you provide a complete example? thanks.

Can you provide a complete example? thanks.

 

So I have this metadata:

 

 

{
  "Items": [
    {
      "Name": "Alien3",
      "ServerId": "Redacted",
      "Id": "9726",
      "IsFolder": false,
      "Type": "Movie",
      "Tags": [],
      "ImageTags": {},
      "BackdropImageTags": [],
      "MediaType": "Video"
    }
  ],
  "TotalRecordCount": 1
}

and I want to add a Tag.

 

So I've tried this:

 

 

and this is what it returns:

So this api was designed for the metadata editor in the web interface. You will need to mimic it's behavior. That means you have to first pull down the item to obtain the complete record, then edit the fields you want to change, then post the changes by sending back the complete item.

 

I would like to add the ability to only send changed fields in the future, but we don't have that right now. Thanks.

Ok.  I've been trying to find a way to get the entire record, but the only way I can find to pull back more data is to add additional fields to the query.  Is there a better endpoint to use?

You would use the items/{id} endpoint to get the full individual item.

to "get" the full record

 

.../emby/users/<user id>/items/<item id>?api_key=<api access token>

 

modify what you need

 

then "post" the full record back in json format
