Continuing the discussion from Not getting files using files-queries:
Hello @Matias.Monday I have the same issue - These files are uploaded from my hard drive and should not be private at all. In fact, querying them with the files endpoint when I know what the ID is returns the file, however I cannot retreive the id via the assets endpoint. What am I missing here?
Hello @totvrdic and welcome to the community!
I hope you like it here 
Would you please send the query you are using, the response you are getting and a screenshot of the board with the item that has the files in it selected and visible in the address bar?
You can also send all of this to appsupport@monday.com if you wish to continue this privately 
Cheers,
-Matias
