Hi @Tinh Nguyen ,
Unfortunately, it is not possible to call the graph API using Azure AD B2C token as graph api does not accept B2C tokens. Please refer to this Github issue.
If you want use Graph to manage resources in Azure AD B2C then you can go through the documentation over here - Manage Azure AD B2C with Microsoft Graph
Supported Graph API operations are -
- Users
- Identity Providers
- User Flows
- Custom policies and custom keys
Please refer to the documentation for more information.
Thanks
Saurabh
