SharePoint site provisioning - set storage quota?


I'm building a Flow to create Modern SharePoint sites via SharePoint API:


"type\": \"Microsoft.SharePoint.Portal.SPSiteCreationRequest\"...


As we use manual site storage quota assignment - is there any possibility to set the site storage quota via SharePoint or Graph API in Flow?

I know the Storage Used and Storage Allocated can be read (GET).


With PowerShell and PnP I'm able to do it but I hope there's also an API to SET it?

Hi Stefan,


Have you considered running the PowerShell to create a site and set the storage quota using Azure Automation and a runbook?  If you set up that piece you can then create a Flow with the action Azure--> Create Job to run PowerShell.  You can then allow your users or admins to run that Flow from within SharePoint, say from a site request list.


Take care!

Hi Ashley,


Thanks for your response. Setting the storage quota via PowerShell in an Azure Function or Runbook is my alternative as Plan B. Unfortunately it doesn't make things easier. So if there is the possibilitiy to do all in the Flow via API I of course would like to do it there.

@cgru3eejc2 - I know this is an old post, but wondering if you ever found a solution?

Hi @jefmeyer - no unfortunately I didn't find an API. Did it in PowerShell (runbook) and call it from the Logic App
