I'm writing a program where I need to set the campaign targeting on ad customizer feed items.
I'm using v201806 of the API.
I can use the ADD and REMOVE operators just fine but i get a operand_not_supported error if I try and SET the targeting.
For now my workaround is to remove all the targeting and then add it all, but this seems a bit messy. i must be doing something wrong.
the operand i'm trying to post contains the campaignId, feedId, feedItemId and of course the operator. What am I missing?
Regards,
Joe
