Trying to add item (jpg image) with thumbnail using Python REST API.

Question

Hi! I am adding multiple images (jpg format) to ArcGIS Portal using Python REST API. So far the part of the code that works (except 'overwrite' parameter) looks like that: addItem_files = {'file':open(addItem_file_path, 'rb')} response = requests.post(refererUrl+'/rest/content/users/' +username+'/'+addItem_portal_folder+'/addItem?' +'token='+portalToken +'&overwrite=True' +'&type='+addItem_type +'&title='+addItem_filename +'&tags='+addItem_tags +'&culture=pl' + '&f=json', files=addItem_files)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ I have hit a wall when trying to add thumbnails in the process. Thumbnails are stored in the subfolder and their names correspond to the original file name ('thumb_*' prefix). The code with thumbnails implemented look like that: addItem_files = {'file':open(addItem_file_path, 'rb'), 'thumbnail':open(addItem_thumbnail_path, 'rb')} response = requests.post(refererUrl+'/rest/content/users/' +username+'/'+addItem_portal_folder+'/addItem?' +'token='+portalToken +'&overwrite=True' +'&thumbnail='+thumbnail_name +'&type='+addItem_type +'&title='+addItem_filename +'&tags='+addItem_tags +'&culture=pl' + '&f=json', files=addItem_files)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Unfortunately there's no result, no thumbnail or even original image. I would appreciate any suggestions how to properly upload file with thumbnails as well with the overwrite parameter. Both the thumbnail and overwrite parameters work when using ArcGIS Portal Directory: /sharing/content/users/user/addItem Also, I am working with both ArcGIS Portal and ArcGIS Server Linux versions 10.4.1. Any help on this is highly appreciated. Thanks!

I am trying to use the Portal REST API and the POST method to add item to the Portal following the API reference I have:

Same thing can be achieved for one file trough the rest directory, but only for one file at the time:

I have found module from ESRI on GitHub that have "AddItem" function which is basically what I am trying to write myself. But I need to dig into that..

Are you mimicking the parameters used when going through the workflow in the browser with the dev tools or Fiddler running?
