I want to upload a file in an API call without saving the file in mendix first, not even in memory (I do not want to use system.FileDocument entity at all). I want the upload to be from the user's file directory. Is there a way to do that?
You can either store files on AWS S3 by using S3 Connector or write your own java action to save files on the Mendix temp folder. you can’t create a new folder on mendix application root and upload your files using java actions it’s restricted by mendix for security reasons.
