Payment gateway setup on Meteorjs for gocashfree.com

Our platform is built on MeteorJS (with iron router). I am integrating a payment gateway of gocashfree. I am able to call payment gateway api. But the problem is that api is returning response on return url which is given while calling api to return on that page after payment gateway done. I am returning back on that url after payment done but not able to find that response object which payment gateway is returning. I can show you the issue via screen share. Gocashfree url [login to view URL]
