		@StatusDescription nvarchar(MAX) OUTPUT)
AS

EXEC usp_ETrade_Auth_Refresh @Profile

DECLARE @URL nvarchar(MAX)
DECLARE @HTTPSessionID uniqueidentifier
DECLARE @Sandbox bit

SET @Sandbox = SQLHTTP.net.AuthParam(@Profile, 'Sandbox')

IF @Sandbox = 1
	BEGIN
		SET @URL = 'https://etwssandbox.etrade.com'

		EXEC SQLHTTP.net.UrlBuilder   @URL OUTPUT,
					      @Profile,

		RETURN
	END
  ELSE
	BEGIN
