Introduction

Applying a site design programmatically using the SharePoint REST API can be a complex task, especially when it comes to waiting for its completion. In this article, we will explore the process of applying a site design using a Power Automate flow and waiting for its completion.

Understanding Site Designs

Site designs in SharePoint are a powerful feature that allows you to create and apply a set of site templates, layouts, and configurations to a new site. This feature is particularly useful for organizations that need to create multiple sites with the same layout and configuration.

Applying a Site Design Programmatically

To apply a site design programmatically using the SharePoint REST API, you will need to use the POST method to create a new site and apply the site design. Here is an example of how you can do this using a Power Automate flow:

POST https://your-sharepoint-site.sharepoint.com/_api/web/ApplySiteDesign Content-Type: application/json

"siteDesignId" "your-site-design-id", "siteUrl": "https://your-sharepoint-site.sharepoint.com/sites/your-site-name"

Waiting for Site Design Completion

However, as you have observed, the number of actions is limited, and you cannot simply wait for the site design to complete using a simple Wait action in Power Automate. This is because the site design application process is asynchronous, and you need to poll the SharePoint REST API to check the status of the site design application.

Using Polling to Wait for Site Design Completion

To wait for the site design completion, you can use a polling mechanism to check the status of the site design application at regular intervals. Here is an example of how you can do this using a Power Automate flow:

GET https://your-sharepoint-site.sharepoint.com/_api/web/GetSiteDesignStatus Content-Type: application/json

"siteDesignId" "your-site-design-id"

You can then use a Condition action in Power Automate to check the status of the site design application and wait for it to complete.

Power Automate Flow Example

Here is an example of a Power Automate flow that applies a site design programmatically and waits for its completion:

# Apply Site Design and Wait for Completion
Step 1: Apply Site Design

HTTP action:

Method: POST
URL: https://your-sharepoint-site.sharepoint.com/_api/web/ApplySiteDesign
Headers:

Content-Type: application/json


Body:{
  &quot;siteDesignId&quot;: &quot;your-site-design-id&quot;,
  &quot;siteUrl&quot;: &quot;https://your-sharepoint-site.sharepoint.com/sites/your-site-name&quot;
}





Step 2: Wait for Site Design Completion

HTTP action:

Method: GET
URL: https://your-sharepoint-site.sharepoint.com/_api/web/GetSiteDesignStatus
Headers:

Content-Type: application/json


Query Parameters:

siteDesignId: your-site-design-id




Condition action:

Expression: @equals(outputs(&#39;Get_Site_Design_Status&#39;)?[&#39;d&#39;][&#39;Status&#39;], &#39;Completed&#39;)
Case: Yes
Next Step: End of flow
Case: No

Next Step: Wait action (wait for 1 minute and repeat)





Step 3: End of Flow

End of flow action
