SharePoint templates (both site and page templates) define the structure and functionality of your SharePoint environment. When trying to replicate a page's layout, identifying the template is crucial. Here are the technical approaches:

# Connect to SharePoint Online
Connect-PnPOnline -Url "https://yourtenant.sharepoint.com/sites/yoursite" -Interactive

# Get Site Template
Get-PnPWeb | Select-Object WebTemplate, WebTemplateId, Configuration

# Get Page Template (for modern pages)
$page = Get-PnPClientSidePage -Identity "YourPage.aspx"
$page.PageLayoutType

using (var context = new ClientContext("https://yourtenant.sharepoint.com/sites/yoursite"))
{
    context.Credentials = new SharePointOnlineCredentials(username, securePassword);
    
    // Get Site Template
    Web web = context.Web;
    context.Load(web, w => w.WebTemplate, w => w.Configuration);
    context.ExecuteQuery();
    
    Console.WriteLine($"Template: {web.WebTemplate}#{web.Configuration}");
    
    // For modern pages
    var file = web.GetFileByServerRelativeUrl("/sites/yoursite/SitePages/YourPage.aspx");
    var page = file.ListItemAllFields;
    context.Load(page);
    context.ExecuteQuery();
    
    var layout = page["PageLayoutType"];
    Console.WriteLine($"Page Layout: {layout}");
}

// Get Site Template
GET https://yourtenant.sharepoint.com/sites/yoursite/_api/web?$select=WebTemplate,Configuration

// Get Page Template (modern)
GET https://yourtenant.sharepoint.com/sites/yoursite/_api/web/getfilebyserverrelativeurl('/sites/yoursite/SitePages/YourPage.aspx')/listitemallfields?$select=PageLayoutType

• STS#0: Team site (classic)
• GROUP#0: Modern Team site
• BDR#0: Document Center
• PageLayoutType: Article: News page layout
• PageLayoutType: Home: Home page layout

If you're getting null values for modern pages, ensure you have proper permissions and verify the page is actually a modern page (classic wiki/web part pages require different approaches). For publishing pages, check the PublishingPageLayout field instead.

SharePoint templates define the structure and functionality of sites and pages. There are two main types:

• Site Templates (e.g., STS#0 for Team Site, BLOG#0 for Blog)
• Page Templates (used in modern and classic pages)

For a quick check without code:

1. Navigate to Site Settings
2. Under "Site Actions", click "Save site as template"
3. The template ID appears in the URL (Template=STS#0)

Here's a PowerShell script using PnP PowerShell:

# Connect to SharePoint
Connect-PnPOnline -Url "https://yourtenant.sharepoint.com/sites/yoursite" -Interactive

# Get site template
$web = Get-PnPWeb
$web.WebTemplate + "#" + $web.Configuration

For modern page templates, use this C# code:

using (var ctx = new ClientContext("https://yourtenant.sharepoint.com"))
{
    ctx.Credentials = new SharePointOnlineCredentials(username, securePassword);
    var page = ctx.Web.GetFileByServerRelativeUrl("/sites/yoursite/SitePages/home.aspx");
    ctx.Load(page, f => f.Properties);
    ctx.ExecuteQuery();
    
    Console.WriteLine(page.Properties.FieldValues["ClientSideApplicationId"]);
}

For classic publishing pages, inspect the Page Layout:

$page = Get-PnPFile -Url "/sites/publish/SitePages/home.aspx" -AsListItem
$page["PublishingPageLayout"]
