Create sharepoint site flow - API

[BR1984]

Hi 

I have a form where my employ fill when they need to create a sharepoint site with a template we have made - now we do it manually from sharepoint where we chose the template and site name and so on.

Can flow with API do this - has anyone tried ? - i know before we could create subsites (old sharepoint) but has never seen with modern sites.

Thanks

Hi @BR1984,

Yes this would be possible via the REST API methods and some Send an HTTP requests to SharePoint actions.

1. Add a Send an HTTP request to SharePoint. Use the Create method from SPSiteManager.

{
  "request": {
    "Title": "@{variables('SiteTitle')}",
    "Url":"https://contoso.sharepoint.com/sites/@{variables('SiteTitle')}",
    "Lcid": 1033,
    "ShareByEmailEnabled":false,
    "Classification":"Low Business Impact",
    "Description":"Description",
    "WebTemplate":"SITEPAGEPUBLISHING#0",
    "SiteDesignId":"00000000-0000-0000-0000-000000000000",
    "Owner":"dennis@contoso.onmicrosoft.com",
    "WebTemplateExtensionId":"00000000-0000-0000-0000-000000000000"
  }
}

2. Add another Send an HTTP request to SharePoint action. Use your new site for the site address field. Use the AddSiteDesignTaskToCurrentWeb method in the URI:

/_api/Microsoft.SharePoint.Utilities.WebTemplateExtensions.SiteScriptUtility.AddSiteDesignTaskToCurrentWeb

{
 "siteDesignId": "@{variables('SPOSiteDesign')}"
}
