Download SharePoint file from Microsoft Graph API using "sourcedoc" ID

I'm trying to download a SharePoint file from the MS Graph /drive/items/xxxx API endpoint. The link I have is in the format https://company-my.sharepoint.com/personal/drive_name/_layouts/15/WopiFrame.aspx?sourcedoc=%7B<GUID>%7D, but the graph API needs some other OneDrive file ID to successfully fetch file metadata.

I have the correct permission scopes, and if I enumerate drive contents I can see the file there.

Is there any way to convert the sourcedoc guid into what is required by the API, or alternatively get file metadata by SharePoint guid?

what you're after is the Shares API. Given a URL like the one you used in your example you need to convert it to a share id value using this algorithm.

So for your example the id be:

u!aHR0cHM6Ly9jb21wYW55LW15LnNoYXJlcG9pbnQuY29tL3BlcnNvbmFsL2RyaXZlX25hbWUvX2xheW91dHMvMTUvV29waUZyYW1lLmFzcHg_c291cmNlZG9jPSU3QjxHVUlEPiU3RA

With this value you can then query the item's metadata using:

https://graph.microsoft.com/v1.0/shares/u!aHR0cHM6Ly9jb21wYW55LW15LnNoYXJlcG9pbnQuY29tL3BlcnNvbmFsL2RyaXZlX25hbWUvX2xheW91dHMvMTUvV29waUZyYW1lLmFzcHg_c291cmNlZG9jPSU3QjxHVUlEPiU3RA/root
