Getting access to a OneDrive DriveItemVersion

Question

Hi there,

Actually I'm trying to access older versions of my Excel files. I can get a list with "/versions". I can get some detail information about a specific version with "/versions/x.0.

But getting the content is not working for me (no specific error message)

Graph Explorer
https://graph.microsoft.com/v1.0/me/drive/items/01Y5BOJUKNFSJVM6VB6J.../versions/2.0/content
   

Is it possible to get access to driveItems based on a DriveItemVersion?
Or download such an old version?

I appreciate your help. Thanks in advance

Hello Stephen Gray,

Thanks for reaching out!

As per the details provided, you're trying to use Download contents of a driveItemVersion graph API in Graph Explorer. For this API, the response content is not available in Graph Explorer due to CORS (Cross-Origin Resource Sharing) policy. You can execute this same endpoint/request in an API client, like Postman and it will work as expected.

Refer this to know about CORS.

Got the CORS error while trying to get the content of DriveItem version using GRAPH API: me/drive/items/{items-id}/versions/{version-id}/content from Graph Explorer.

Cors_graph

Got the successful response from Postman with same API endpoint.

Cors_Postman

Please note that, we can't get the content of current version using above graph API. To get the content of current version use: me/drive/items/{items-id}/content

Hope this helps.

Use the /versions/{version-id}/content endpoint to get a URL that will allow you to download a specific version. You can read more about it here.
