Move documents from SharePoint sub site document library to parent site document library ?

There's actually not an action in Nintex Workflow for Office 365 to copy a document from a subsite to a parent site.  The "Upload Document" action only works within the same site.

I had a similar requirement of copying a document from library in the parent site to a library in a child subsite.  I was able to accomplish this by first using the Web Request action with the Copy.asmx web service and the GetItem method (to get document information in XML format), then using the Query XML action (to get the document stream information to pass), and finally using the Web Request action with the Copy.asmx web service and the CopyIntoItems method (to copy the document to the subsite library).

In your case, you could use this method in a workflow on the document to copy it down to the subsite and then use the Delete Item action to delete the current document.

It's the "Copy Document" that only works within the same site.  Are you talking about the "Office 365 Upload File" action?  I do not see the "Office 365 Upload a document" action.

‌ Do you have any idea on this.

 Thank you for your response. Yes, I tried using rest api as well. Rest API has moveto and copyto methods to move the documents from one document library to another library. But this will execute only when we are moving the files with in the site not across the sites.
