Does AddFeatures endpoint accept WKT format in the geometry of each feature?

Hi everyone,

Did anyone try to add features using the /rest/services/.../{layerid}/addFeatures endpoint and using WKT json input for the geometry?

I find the documentation quite ambiguous when it shows:

For the Features parameter: "The structure of each feature in the array is the same as the structure of the json feature object returned by the ArcGIS REST API."
For the Geometry in json feature object: geometry—The feature geometry. It can be any of the supported geometry types. It is a JSON object as defined in the Geometry Objects documentation.
Geometry Objects documentation: Appears the json WKT-based syntax as a valid syntax to represent geometries.

I tried in the add features web form the following input:

[{ "wkt": "GEOGCS[\"GCS_WGS_1984\",DATUM[\"D_WGS_1984\",POINT[\"WGS_1984\",-79.419591,43.647131]],PRIMEM[\"Greenwich\",0],UNIT[\"Degree\",0.017453292519943295]]", "attributes": { "ProductId": 10175 } }]

As you can see in the attached image, the endpoint ended with success adding a new item with objectid 3636.

But this is the result of the features query after the "creation". It seems to create an empty/invalid geometry storing only the attributes but no geometry information.:

{
 "objectIdFieldName": "OBJECTID",
 "globalIdFieldName": "",
 "geometryType": "esriGeometryPoint",
 "spatialReference": {
  "wkid": 4326,
  "latestWkid": 4326
 },
 "fields": [
  {
   "name": "ProductId",
   "alias": "ProductId",
   "type": "esriFieldTypeInteger"
  }
 ],
 "features": [
  {
   "attributes": {
    "ProductId": 10175
   }
  }
 ]
}

My doubts are:

Is WKT format allowed as geometry input format in this endpoint? In case it is not allowed, why did it end with success instead of a wrong geometry "input format/invalid geometry" message?
In the other hand, if it is because of a wrong input WKT json, I need to know how to create a valid WKT json for points and polygons (I could not find enough esri documentation or topics in this forum talking about the WKT format when querying/adding geometries)
Is there any way to obtain from the API query endpoint, the features within a layer with the geometry in WKT format? I can only see PBF, Json and GeoJson as output formats. In case I could query an existing valid geometry and get the geometry in WKT, maybe I could use it as input in the addfeatures web form and try it.

If I use the normal json geometry for a Point, it works:

[{ "geometry": { "x": 12.474212758000021, "y": 45.662661214000025 }, "attributes": { "ProductId": 10175 } }]

Any help would be appreciated!

Thanks!
