-## 8. Post Request

 This sample sends an email. The request body is constructed using the provided models.
 Ensure you have the [right permissions](https://docs.microsoft.com/en-us/graph/api/user-sendmail?view=graph-rest-1.0&tabs=http#permissions).
 
+Setup includes:
+1. "App Registration > Authentication > Platform: Mobile and desktop applications" with redirect_uri specified as http://localhost
+2. "Mail.Send" permissions, potentially requiring admin consent
