Install Lyoness (Tradedoubler) Redirect and Tracking Pixel Code on WordPress/Woocommerce.

Attached are the implementation manual and sample codes. If you accept the project, I will forward you the login details and unique details to change in the sample code. My client has applied to become an advertiser on [login to view URL] . She her application was accepted and now we need to install the attached redirect and tracing pixel on 2 of her websites. The problem is that Lyoness uses a company called Tradedoubler to manage their tracking and I can't seem to find a plugin or any other quick solutions for WordPress. Both Websites are built on WordPress and use the WooCommerce plugin to manage the store. The websites are [login to view URL] (International, Sells items in USD. $) and [login to view URL] (Local Store, Currency is the South African Rand. ZAR) What I will need to be done: 1.) I will need the redirect to be set up on both websites as per instruction on the implementation manuals. 2.) I will need the tracking pixel to be installed on the confirmation/thank you page in WoCommerce as per instruction in the manual. 3.) I will need this implementation to be done in a way so that it doesn't get replaced/removed when I upgrade WordPress or and Plugins. Thanks in advance.
