is there a way i can download these documents

As discussed in the other thread, for non-downloadable files like this, you should use the "export" functionality instead. In the .NET SDK, that's available as ExportAsync.

can i also export google imported files with same method

1. how can i download comments of the paper document when i download html it does not give me comments 

2. can i get some zip file or something where i can get all the images and attached documents of that paper document 

if not how can i get images and other attachments from this html or paper file

and also there is this endpoint available 

https://api.dropboxapi.com/2/paper/docs/download

 so can't you download paper docs with this endpoint

[Greg-DB]

Yes, you would use the export functionality to download any items with files with exportInfo.exportAs set, such as Google docs.

The Dropbox API unfortunately doesn't offer the ability to list or read comments on Dropbox Paper docs, but I'll pass this along as a feature request.

There isn't a separate call for downloading images/attachments. Anything in the Paper doc will be included in the exported data itself.

The /2/paper/docs/download endpoint is an endpoint for downloading legacy Paper docs, that is, Paper docs that are not in the Dropbox filesystem. You can find more information here. For .paper files in the filesystem, you should use the export functionality as discussed above.

currently i am exporting file how can i get exported data that includes images 

[Greg-DB]

Images are included in the exported HTML, via an <img> element.
