How to send a file to other application

I want to send a file (.obj) from application build on Cuba platform to another application build on some other framework using HTTP protocol, so How this can be achieved by using Cuba Studio?

Hey!

You can use the file_download REST API method Cuba App in another application build on some other framework using HTTP.
Using JAVA HTTP client, send FileDescriptor to another application. Next, using access token, download the file from another application file via the REST API.

Or pay attention to the file_storage methods
