I am searching for a solution which will work with the combination of docuware and sharepoint online. 

As I know currently docuware is supporting only for on-premises. 

I want to know any new updates got released for SharePoint online?

Using javascript is it possible to call the REST apis of docuware? Any help blogs are available to understand?

Or is there any alternate solution to use some other service to use between SharePoint online and Docuware cloud?
