Maira MehtabMaira Mehtab Sep 22, 2026 869 views

Question details

The user wants to provision a Microsoft 365 group-connected SharePoint team site using REST API endpoints, specifically within a Power Automate workflow.

Product
SharePoint Online / Power Automate
Device & OS
not provided
Scenario
Automating site creation workflows involving Microsoft 365 group-connected sites rather than classic site collections.
Observed behavior
Standard REST endpoints in Power Automate support creating classic or standard team sites, but lack direct support for provisioning Microsoft 365 group-connected sites due to differences in the provisioning model.
Before you start

Ensure you have the necessary SharePoint Administrator permissions and are familiar with the Microsoft Graph API, as managing Microsoft 365 Groups typically requires Graph endpoints rather than standard SharePoint REST APIs.

Solution 1Recommended

Consult Microsoft Power Platform Communities for Graph API Guidance

Due to the evolving nature of Microsoft 365 provisioning, consulting the official developer communities is the most effective way to get up-to-date API implementations.

Power Automate REST endpoints support standard SharePoint team sites, but direct creation of Microsoft 365 group-connected sites is heavily dependent on the current Microsoft 365 provisioning model. Experts typically recommend leveraging Microsoft Graph API instead of traditional SharePoint endpoints for this task.

1
Navigate to official forums

Open your browser and go to the Microsoft Power Platform Community or Microsoft Q&A platform.

2
Create a detailed inquiry

Start a new discussion thread and ensure you apply the 'SharePoint Development' and 'Power Automate' tags to reach the right experts.

3
Provide your workflow details

Include the specific Power Automate actions you are using, the REST endpoints you have attempted, and your required site configuration (such as group owners and privacy settings).

4
Request Graph API workarounds

Ask the community for updated documentation or examples of using the 'Send an HTTP request' action with Microsoft Graph endpoints to create the underlying Microsoft 365 Group.

API Limitations: Standard SharePoint REST endpoints often do not support direct group-connected site creation. The Microsoft Graph API is typically required for full Microsoft 365 Group provisioning.

Frequently Asked Questions

Why can't I create a Microsoft 365 group-connected site with standard SharePoint REST APIs?

Standard SharePoint REST APIs were originally designed for traditional site collections. Microsoft 365 group-connected sites require the creation of an underlying unified group in Azure Active Directory, which is handled via the Microsoft Graph API rather than legacy SharePoint REST endpoints.

Can Power Automate create SharePoint team sites automatically?

Yes, Power Automate can automate site creation. You can use the 'Send an HTTP request to SharePoint' action for standard sites. However, for group-connected sites, you must utilize HTTP actions targeting the Microsoft Graph API, provided the workflow has the appropriate App Registration and API permissions.

What is the recommended API alternative to create a Group-Connected site?

Developers should use the Microsoft Graph API. Specifically, by making a POST request to the '/groups' endpoint to provision the Microsoft 365 Group, Microsoft automatically provisions the associated SharePoint team site in the background.
