Dear all.

I have recently been working on a file upload system using the HTTP Connector.
I am planning to upload the file to BIOVIA Foundation Hub.
"https://:9953/foundation/hub/doc/fileService"
says it has an API for file upload, so I'm planning to use it.
I created a protocol as a sample, but it does not work...

I looked at past related articles in the user community and found a lot.
Ex.

However, I would like more information to understand this system :-(.
Does anyone have any relevant information or samples?
