remote API - session data not available for saveurl

remote API - session data not available for saveurl

I am using Zoho remote API in one of my web projects. The PHP script handling saveurl does session check for authorized users. But the API does not seem to post the session information to my remote server. I even tried appending PHPSESSID=..... to the saveurl specified in the initial editor form but it does not do anything either. The reason I believe is because the POST to my remote server is from a zoho server instead of my local browsor.
So I am wondering how I can integrate your remote API and at the same time have my application secured with PHP session.

Thanks,
