How to Create a SharePoint Group-Connected Team Site with REST API
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.
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.
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.
Open your browser and go to the Microsoft Power Platform Community or Microsoft Q&A platform.
Start a new discussion thread and ensure you apply the 'SharePoint Development' and 'Power Automate' tags to reach the right experts.
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).
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.

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.
