eBay API - How to include affiliate tracking information in GetItem call's ViewItemURL parameter

Question

As far I know some eBay API call like:

1. findItemsAdvanced
2. getSimilarItems

have an input parameter to specify the Affiliate trackingId, networkId and other info that allow me to identify my affiliate and then return a ViewItemURL that have included affiliate tracking information.

How do I pass my affiliate data to the API call GetItem, so its response field ViewItemURL has included my affiliate tracking information?

Answer 1

Why not use the GetSingleItem call in the Shopping API rather than GetItem in the Trading API?

GetSingleItem

It does the exact same job, and it allows URL parameters in the call to be used to "affiliatise" the returned URL.
