This is a follow up to my previous post: Moving Files with SharePoint Online REST APIs in Microsoft Flow, which explains how to move/copy files with Microsoft Flow using the SharePoint - Send an HTTP request to SharePoint
action and the SharePoint Online SP.MoveCopyUtil
REST API.
This post demonstrates using a similar approach, but using the CreateCopyJobs
and GetCopyJobProgress
APIs to copy files from one site collection to another.
I suggest reading the previous post first for context if you haven't already.
