Leasing payment module

Hello.
Can anybody help?
I have the leasing payment module. Seems working fine if customer not interrupting the session when signing deal with the leasing company. If signing was interrupted, This leasing company sending the e-mail to the customer with a link to follow up his signing. And when the customer deal is signed, this leasing company send to my callback link

http://my-e-shop/e-shop/index.php?route ... g/callback

confirmation about this deal and I receive this url :

http://my-e-shop/e-shop/index.php?route ... rderId=123

How to grab this order_id from address bar and follow up the session with this order_id to make checkout/success and post order status processed?

Thank you in advance.

getting data from the url, you can use $this->request->get on OpenCart.
