I am trying to create a form, wherein the users should be able to upload CAD related files (.drw or .asm). But the database collection allows only images and documents.
I have tried writing a backend code to connect to a third party service. And I am trying to use a XMLHttpRequest object to connect to this service. But I believe that Wix does not support XMLHttpRequest object as of now.
I also know that there are apps like Dropbox upload and anyfile upload which could support custom File uploads. But those apps just won't fit my requirement. This makes my options from limited to none.
So any pointers in building/fixing this upload issue?
