Introduction
Many times, a site is already created, and we need to apply configuration in the existing site to achieve some level of consistency. How can we achieve it?
To achieve this kind of implementation, use site template and site scripts to automate provisioning to the existing modern site or create a new site using site templates which is available in your organization tenant.
In the previous blog, I cover how to create a new site Script and Site Template using Rest API in Power Automate.
I hope, you have already created the Site Script and Site Design. If you want to create then you can click here.
Today we are looking at how developers can get an existing Site Template and Apply it to SharePoint's existing site using Rest in Power Automate.

Filter Site Template By Name
Select “Condition” from the list of connectors.
Compare Title to Site Template Name. The title will be returning from Parse JSON action.
When you select Title from it, It would convert in Foreach loop because Get Site Template returns all site templates from the tenant.
![Get Existing Site Template and Apply to Existing SharePoint Site]()
If Condition is “True” then we will apply the Site Template to the Existing Site.
Apply Site Template to existing SharePoint Site
Click on “Add Action” inside the True Section of Condition.
Select “Send an HTTP request to SharePoint”.
Select Site from the list.
Select Method “Post”.
Add Below URL-to-URL section.
/_api/Microsoft.SharePoint.Utilities.WebTemplateExtensions.SiteScriptUtility.ApplySiteDesign
The header Should be as below.
{
"Content-Type\n": "application/json;charset=utf-8",
"accept": "application/json;odata.metadata=minimal",
"odata-version": "4.0"
}
The body Should be as below.
{
"siteDesignId": "@{items('Apply_to_each')?['Id']}", // ID from existing item in from For each loop
"webUrl":"https://dev1802.sharepoint.com/sites/Demo3" // Site where you want to apply site template
}
![]()
Full Flow would be like as below.
