thanks for your suggestions and the links!
Unfortunately, these approaches do not solve my core problem. I‘m aware of the possibility to retrieve metadata and the _vti_history URL for previous versions using the REST API or to manually download historical versions via browser.
However, the challenge is to programmatically download the actual file content of a specific (major) historic version in a Power Automate (Cloud Flow) scenario.
So far, all attempts (including HTTP calls to the _vti_history URL and “Get file content using path”) either result in 401/404 errors or always return only the latest file version, due to SharePoint Online’s security and authentication mechanisms.
To clarify:
-
Manual download in the browser works fine – but I’m looking for a 100% automated approach.
-
I do not want to restore or copy the file version as a workaround.
-
Neither the Graph API nor the standard SharePoint connectors allow access to the binary content of a specific previous file version in a flow.
As far as I can tell, there is currently no supported or documented way to achieve this directly in Power Automate.
If there are any new APIs, preview features, or alternative methods for this scenario, I’d appreciate any pointers!
Thanks anyway for your help – maybe this will be possible in the future!
Best regards,
Rene
