How to create and change a folder's content type using the MS Graph API

[Nigel Witherdin]

Hi,

I need to create a folder using the Graph API, then change its content type and set metadata against it.

Ideally I would like to use SharePoint end points (/site/) to:

- Create the folder in a specific library

- Change the folders content type to a custom one

- Update metadata on the folder

Can anyone please provide me an example of doing this?

Many thanks!

• Create the folder: 

  POST /drives/{drive-id}/items/root/children

  {

  "name": "{name}",

  "folder": { },

  "@microsoft.graph.conflictBehavior": "fail"

  }

• Get the created folder's item id: 
  GET /drives/{drive-id}/items/root:/{folder-name}?expand=sharepointIds
• Update folder's content type and metadata:
  

  PATCH /sites/{site-id}/lists/{library-name}/items/{item-id}

  {

  "contentType":

    {

      "id": "{content-type-id}"

    },

  "fields":

    {

    "field_1_name": "{field_1_value}",

    "field_2_name": "{field_2_value}"

    }

  }
