Need PHP document integrated with REST API

My business is an affiliate network where website owners place links with tracking code on their website and when a visitor clicks on the link and is taken to an advertiser site and then makes a purchase, the website owner gets paid. The affiliate network is mostly product-based, so I need a way to integrate product offerings and the website owner-specific tracking links for each product. I have a sample product page at [login to view URL] The tracking links are generated through a platform I am using called Ad Cumulus. Notice that on the [login to view URL] pages there are two instances of code being shown. What I need is to connect the platform account (after the website owner has logged in) to the php page above so that the tracking links are automatically generated for that website owner specifically, so sales can be tracked and placed toward their account specifically. The platform has REST API integration, and the documentation is attached. The Method Offer: generateTrackingLinks is the part that I think is what is needed (section 5.2.2.11) Please answer the following questions: 1. Is this possible through the API they provide? 2. Is there another way you would do it instead? My main issue is that through the platform, you are unable to do a mass import of thumbnail images for each product, and I would have to do it manually. This combination of the PHP document and the API integration seem to be my only hope, unless there is another way I do not know of to achieve this using the API. 3. How long will this project take? Please be specific. Thank you! Liz
