How to Create a SharePoint Page via Graph API and Power Automate

Creating a SharePoint page programmatically can be highly beneficial for automating content management within an organization. By leveraging Microsoft Graph API and Power Automate, you can automate the creation of SharePoint pages without manual intervention, ensuring consistency and efficiency.

This article will guide you through the process, from setting up Graph API permissions to building a Power Automate flow that creates and customizes a SharePoint page dynamically.

1. Prerequisites for Using Graph API and Power Automate

Before you start creating a SharePoint page programmatically, ensure you have the following:

• Microsoft 365 subscription with SharePoint Online.
• Global Admin or SharePoint Admin access to configure API permissions.
• Azure AD App registration to obtain the necessary permissions.
• Power Automate (Flow) access to automate the page creation.
• Graph API permissions to interact with SharePoint sites.

Ensure that your account has sufficient rights to create pages in your target SharePoint site.

2. Setting Up Graph API Permissions for SharePoint

To create SharePoint pages via the Graph API, you need to configure the right permissions in Azure Active Directory:

a) Register an Application in Azure AD:

1. Go to Azure Portal → Azure Active Directory.
2. Navigate to App registrations → New registration.
3. Provide a name for your app and select Accounts in this organizational directory only.
4. Click Register.

b) Assign API Permissions:

1. In your registered app, navigate to API permissions → Add a permission.
2. Select Microsoft Graph → Delegated permissions.
3. Add the following permissions:Sites.ReadWrite.All (Required for creating pages)Sites.Manage.All (For managing page content)Sites.FullControl.All (If deeper control is needed)
4. Click Grant admin consent to approve permissions.

c) Generate Client Secret:

1. In the Azure app, go to Certificates & secrets → New client secret.
2. Set an expiration period and copy the Client Secret Value (It will not be visible later).

d) Capture Necessary Information:

• Application (Client) ID
• Directory (Tenant) ID
• Client Secret Value

These details will be used in Power Automate to authenticate with the Graph API.

3. Using Graph API to Create a SharePoint Page

Once your app is registered and permissions are set, you can use Graph API to create a SharePoint page.

a) Construct the Graph API Request

Use the following HTTP POST request to create a modern SharePoint page:

Endpoint:

POST https://graph.microsoft.com/v1.0/sites/{site-id}/pages        

Headers:

{ "Authorization": "Bearer {access-token}", "Content-Type": "application/json" }        

Body:

{ "name": "New Page", "title": "Automated SharePoint Page", "pageLayout": "Article", "publishingState": { "level": "published", "versionId": "1.0" } }        

b) Obtaining the site-id

You can retrieve the SharePoint site ID by making this request:

GET https://graph.microsoft.com/v1.0/sites/{tenant-name}.sharepoint.com:/sites/{site-name}        

c) Running the API Request

You can test your request using Postman or Graph Explorer before integrating it into Power Automate.

4. Automating SharePoint Page Creation with Power Automate

To automate the process using Power Automate, follow these steps:

a) Create a New Flow

1. Log in to Power Automate and click Create → Automated Cloud Flow.
2. Choose When an HTTP request is received (if you want to trigger it externally) or another trigger like Recurrence.
3. Click Create.

b) Configure the HTTP Request to Graph API:

1. Add a "Send an HTTP request" action.
2. Set Method to POST.
3. URI: https://graph.microsoft.com/v1.0/sites/{site-id}/pages
4. Headers: Add:
5. Body: Paste the JSON request body mentioned in the previous section.

c) Handle Authentication:

• Add a "Get Access Token" step before making the API request.
• Use Azure AD OAuth 2.0 with:Client IDTenant IDClient SecretScope: https://graph.microsoft.com/.defaultGrant Type: Client Credentials

d) Test the Flow:

• Run the flow manually or trigger it based on an event (e.g., form submission).
• Verify the page creation in SharePoint.

5. Customizing the SharePoint Page

After the page is created, you can add web parts dynamically. Use the PATCH request to modify the page:

Example API Request to Add a Web Part:

PATCH https://graph.microsoft.com/v1.0/sites/{site-id}/pages/{page-id}        

{ "sections": [ { "webparts": [ { "type": "Text", "properties": { "text": "Welcome to our automated SharePoint page!" } } ] } ] }        

This allows you to add text, images, and other content to the page dynamically.

6. Deploying and Maintaining the Automation

• Schedule the Flow: Run the flow on a schedule or trigger it based on external events.
• Monitor Execution: Use Power Automate's Run History to track errors.
• Refine API Calls: Test and modify the API requests to enhance the page structure.

Summary

Using Microsoft Graph API and Power Automate, you can efficiently create SharePoint pages with dynamic content and automation. By integrating API calls within Power Automate, you eliminate manual page creation, ensuring consistency across your SharePoint environment.
