How to get document GUID from revit model

Question

I'm trying to get a model thumbnail and I tried this. I can get an RVT thumbnail if I don't use the guid param, but I want to use a view thumbnail, so I need to use the guid. I'm new to Autodesk, how can I get the guid?

You need to parse the manifest with this endpoint GET Manifest. You will receive this kind of response:

    {
  "type": "manifest",
  "hasThumbnail": "true",
  "status": "inprogress",
  "progress": "99% complete",
  "region": "US",
  "urn": "dXJuOmFkc2sub2JqZWN0czpvcy5vYmplY3Q6bW9kZWxkZXJpdmF0aXZlL0E1LnppcA",
  "derivatives": [
    {
      "name": "A5.iam",
      "hasThumbnail": "true",
      "status": "success",
      "progress": "99% complete",
      "outputType": "svf",
      "children": [
        {

          "type": "geometry",

            {

            {

            },
            {
              "guid": "34dc340b-835f-47f7-9da5-b8219aefe741",
              "type": "resource",

              ],
              "mime": "image/png",
              "role": "thumbnail"
            },
            {
              "guid": "299c6ba6-650e-423e-bbd6-3aaff44ee104",

              "mime": "image/png",
              "role": "thumbnail"
            }
          ]
        }
      ]
    }
  ]
}

In the derivatives array, you should find an object with "outputType":"SVF" or "SVF2" (depending how you translated your file). Then in its children, you should get all your viewable:

• "type": "geometry"
• "role" : "2d" or "3d"

You can use the guid of these viewable to get the view thumbnail instead of the default one.
