Keepeek - How do I use a specific form definition for uploaded media ?

Follow the steps above for media creation, but add a kpk:form entry in the POST request in folder's media collection :

POST /api/dam/folders/{folderId}/medias
Content-Type: application/json

{
  "_links":
  {
    "from": 
    {
      "href": "http://baobab.keepeek.com/api/dam/files/df1234ac"
    },
    "kpk:form": 
    {
      "href": "http://baobab.keepeek.com/api/dam/forms/6"
    }
  }
}

The available forms can be retrieved by a GET on /api/dam/forms
