   Every request should have two headers set with your game credentials :
   
  -|Header     |               |
  +|Header     | Value         |
   |---        |---            |
   |x-apikey   |Your API key   |
   |x-apisecret|Your API secret|
  
positive.code: 
  Both `gamer_id` and `gamer_secret` are returned by `/v1/gamer/login`.
  
  It is your responsibility to store these to help the user log in later (in RAW mode).
  
  
  ### Login [POST]

  After login has been called, HTTP Basic Authentication will be used to authenticate every request.

  |---        |---            |
