Uploading document to external server

How can I implement the functionality to upload the currently opened document to an external server using a plugin in the OnlyOffice web version? I have a REST API in my application, and I want to use the plugin to upload the currently opened docx file to that API.


Could you please provide us with details of desired scenario?
