It seems that the Azure AD Graph API made it possible to create a service principal via the REST API endpoint shown below. I am looking for the same functionality in the Microsoft Graph API, yet it doesn't seem to exist in v1.0 or beta.
Does anyone know of a way to achieve this through the Microsoft Graph API?
From Azure AD Graph API:
POST:
https://graph.windows.net/{tenantId}/servicePrincipals?api-version=1.6
Authorization: Bearer {access_token}
{
"appId": "00000003-0000-0000-c000-000000000000",
"accountEnabled": true
}
