Graph API - HTTP Auth

[smerchant]

I am trying to use Graph API but I am struggling to get a token.  I used postman to get the token which worked fine.

I need to make a post request to graph API to create a group. 

Should I be https://login.microsoftonline.com/cbc8a2f1-a4da-4dac-95b6-221568205810/oauth2/v2.0/token or /authorize? and

Should I put client_id, secret etc. in the body?

I am making a post request to https://login.microsoftonline.com/tenentid/oauth2/token with client_id={clientID},scope=https://graph.microsoft.com/.default, client_secret={mysecret} and client_type=client_credentials

I also tried to follow this but this had no success. 

https://developer.microsoft.com/en-us/graph/docs/concepts/auth_v2_service

I am getting the following error:

  "error": "unauthorized_client",
  "error_description": "AADSTS70001:

   Bad Reqeust

Thanks

Managed to resolved this.  I needed to create web app rather than native app in the Azure and endpoint needed to be like:
https://login.windows.net/tenant/oauth2/token?api-version=1.0
