Guzzle 6 and Oauth 2

Hey Everyone,

I am looking to get some data from Todo ist and honestly just improve my knowledge of Guzzle.

I am running into a little roadblock when working with Oauth2.

Here is the doc from todoist on Authorization:

$ curl "https://todoist.com/oauth/authorize"
-d "client_id=0123456789abcdef"
-d "scope=data:read,data:delete"
-d "state=secretstring"

How could I accomplish this using Guzzle 6 and Laravel?

Anything would be greatly appreciated!

Thank You
