[REST] Logging in with an existing auth token

[hacker1024]

When opening the Pandora Web client, after having signed in already, it seems to log In with a request like the following, with an empty password string and a populated existingAuthToken field:

POST https://www.pandora.com/api/v1/auth/login

{
  "existingAuthToken": "<token>",
  "username": "[email protected]",
  "password": "",
  "keepLoggedIn":true
}

The existing auth token is always the one that was received when logging in previously.

Upon replicating this request, however, I get the standard invalid credential error:

{
  "message": "Invalid username and/or password",
  "errorCode": 0,
  "errorString": "AUTH_INVALID_USERNAME_PASSWORD"
}

Does anyone know what's going on here?

Closing as this is no longer relevant (#45)

{
"existingAuthToken": null,
"keepLoggedIn": true,
"password": "dfssdf345",
"username": "[email protected]"
}

{
"message": "The request could not be validated",
"errorCode": 0,
"errorString": "INVALID_REQUEST"
}

how can i get existing auth token?

The only way now is through the JSON API
