Youtube playback

[DGrandes]

Sorry I haven´t explained well, 

I don´t want to stream in LM.

I want to send an order from LM to spotify acount and spotify speakers/devices (play specific playlist, pause, get status...) and I can do it with manual token but it expires.
When I try to get token by script with this script I can´t do it.

Code:

local headers_token = {
    ['Authorization'] = "Basic "..Id_Psw_Encode64,   
  }
function Data_Pedir_Token ()
  url = "https://accounts.spotify.com/api/token"
  data = json.encode({
      ['grant_type'] = "client_credentials",
    }) 
  --log(data,url)
  return data, url
end

function Comando_token (data,url)

  headers = headers_token
  url = url
res, err = dorequestPostSpoty(url, headers,"POST", data)
  log(res,err)
  resjson = json.decode(res)
  if resjson[1] == nil then
    return nil
  end 
  return resjson

end

function PedirToken ()
  local data,url = Data_Pedir_Token ()
  Comando_token(data,url)
end



PedirToken ()

It is posible?
