Hi Rik,
You can see what each GET parameter does here:
In this case,where you have ?id=79863578, that represents line Item 79863578 within order 132530738.
Which in this case would be:
http://www****ntybabynames?channel=4979 (****s are there for privacy)
The reason you need to run a report is that multiple creatives can be associated to the same line item and, at the time of ad serving, which creative was served is not known. If you only have 1 creative per line item, you could in theory download the
LineItemCreativeAssocation from the LineItemCreativeAssociation service using
getLineItemCreativeAssociationsByStatement with a filter of "WHERE lineItemId=79863578".
I highly suggest using a report though since it should have all the information you need. If you need any code examples showing you how to generate a report, please let me know.
Thanks,
