Hi Jacs,
Thanks for reaching out. With regards to your concern, you can get the IDs of your shopping campaigns then you can filter them out with
CampaignID. But, there is no way to directly filter placements from shopping campaigns. You could also potentially filter by
ClickType, if certain click types only happen on shopping ads.
Let me know if you have any questions.
Thanks,
