GET parameters and disallowed characters (Google API)

[eluser]dsloan[/eluser]
I'm trying to interface with Google Calendars using the Google API and am encountering a problem with the response that is returned from Google. As part of the initial authorisation process a call is made to the Google API which displays a remote page asking for access approval, and then redirects the user back to the original URL but with a security token appended to the URL (as a GET parameter). However CI throws an error saying that "The URI you submitted has disallowed characters".

For example, if the original URI is http://www.kpoint.co.uk/index.php/diary then after the Google access request page the browser is redirected to http://www.kpoint.co.uk/index.php?token=123456

Any ideas on how to get around this?

Thanks,
Diarmid Sloan

Got this sorted - the API call has stripped the controller name off the requesting script name and is appending the token to the index.php filename itself.
