I need to enable a user upload option in my site. Once the user uploads, i need to save the uploaded file in a third party service. But I am finding it extremely difficult to do that.
1. Is it possible to upload CAD files onto the Data collections? The only allowable files are images and documents, as of now.
2. I am not able to use XMLHttpRequest in my backend code. It says 'it is undefined'. So is it possible to use Wix-fetch functions to upload a file onto a third party service?
3. And suppose if we cannot use Wix-fetch functions to upload files, then what else can we use to achieve it?
