How to upload files with the API

The form I have created has file upload fields. I'm trying to create submissions via the api, but I can't upload the files, only the plain text fields. How do I upload files with the java api?

Hello snewcomer,

I would suggest you to please contact our API team and they will be the right person to guide you on this. You can send then an email at api@jotform.com.

Thank you!
