What does Articulate Storyline need in order to resume place?

I am using TinCan to communicate to Articulate Storyline. I notice that when it boots up, it sends a GET request for a /state . I'd love to return it something, but I could not find anywhere in your documentation what exactly it needs.

This is what it sends to me :

   {"registration"=>[""],

   "activityId"=>["6LHIJumrnmV_course_id"],

   "actor"=>["null"],

   "stateId"=>["resume"],

   "Authorization"=>[""],

   "AWSAccessKeyId"=>["secretAIVBsecretZNEDsecret"],

   "Signature"=>["3/WTs72secretDEqsecret="],

   "Content-Type"=>["application/json"],

   "Expires"=>["1396359848"],

   "method"=>"GET",

   "any"=>[:OPTIONS, :POST],

   "controller"=>"quizzes",

   "action"=>"state",

   "quiz"=>{}}

So from here I assume that an LRS would look up this ActivityID, and its user, and then return to them a "state". So my question to you is, what *exactly* does your Articulate Storyline need in order to resume to a specific state?

To further explain, because I am ignoring these state requests, a popup appears that says, "Would you like to start off where you left off?" ( or something of similar wording ), and it will present these options to me, even if I'm using a new browser and using the Articulate file for the very first time. If I click "yes", your app doesn't know what to do because it doesn't have any information on what the "state" is of where the user left off at. This is because I did not respond to that `get` request looking for the state.

I imagine the state would be encapsulated inside of some kind of Hash or JSON block like my example above. I just need to know what parameters and values it would have to be set to. 

If I were to guess.. I would assume that the values would be the name of the activtyID in the activity node of the page such as `6LHIJumrnmV_course_id` .

Thank you.
