Implementation of TradeDoubler Tracking

Hi,

I need some help regarding implementation of TradeDoubler tracking into OpenCart. I want to announce the products in my OpenCart store on an online market place (kelkoo) which uses TradeDoubler tracking. I tried to find some extension which does TradeDoubler tracking, but there is no such extension for OpenCart, and I searched technical description on the internet, but I didn’t find any useful stuff.

On the page that confirms that an order has been placed, some information must be sent to TradeDoubler to report the sale. This information includes an eventID and organizationID, which supplied by Kelkoo. Some information about the sale also needs to be reported. This must include order value and order number. Order value should include VAT and shipping and the order number must be a unique value for each order. All this information is reported using a IMG -tag.
e.g. <img src="http://tbs.tradedoubler.com/report?orga ... rrency=DKK" />

Could someone please advise implementation that? Perhaps It needs few lines to include into checkout scripts. I got some short information how it can be implemented:

Thanks for any help and advice.
