Not Receiving AccessToken on Simulator

Question

My Fulfilment End Point isnt receiving accessToken. Is this normal? Becouse when im on the simulator it doesnt really ask to login to my authorization end point thus, it wont get a access token. My Oauth is working perfectly after tesing with Oauth Play Ground.

action.json

    {
"accountLinking": {
    "clientId": "",          // SENSITIVE INFORMATION BLANK
    "clientSecret": "",       // SENSITIVE INFORMATION BLANK
    "grantType": "AUTH_CODE", 
  "authenticationUrl": "",      // SENSITIVE INFORMATION BLANK
  "accessTokenUrl": ""          // SENSITIVE INFORMATION BLANK


  },
  "actions": [{
        "description": "",
        "name": "MAIN",
        "fulfillment": {
            "conversationName": "PASS TEXT"

                    "talk to APP NAME"
                ]
            }
        }
    }],

 "conversations": {
        "PASS TEXT": {
            "name": "PASS TEXT",
            "url": ""  // MY FULFILLMENT END POINT
            "fulfillmentApiVersion": 2
        }
    }
}

Answer 1

Think you have to manually complete that part - if you look in the response, you'll see a URL - copy/paste and run that, it should complete the account linking process - https://developers.google.com/actions/identity/account-linking

"In the Log area, copy and paste the URL from the debugInfo.sharedDebugInfo.debugInfo field into your web browser. You will be redirected to the authentication URL for your own server that was specified in API.AI or in the Actions Console."

Answer 2

Account linking is done through the Actions Console at https://console.actions.google.com/

From the "Overview" menu item, you'll need to get to step 5: Account Linking.

In there, you can set your endpoints, scopes required, etc.
