Using app tokens

[tarqd]

There should be a method to perform API requests with the app token.
You can get by requesting this URL

/oauth/access_token
    ?grant_type=client_credentials
    &client_id=11111111
    &client_secret=9999999999

You need to do this to make calls to certain functions (such as sending a notification)
