Hi.
We're using the 201710 api.
We maintain a database of campaign, adgroup and shared keyword criteria that we need to keep in sync with adwords.
For that, we need to be able to efficiently query removed keywords, both negative and positive, so as to avoid having to always query all keywords to update the database.
Campaign criteria(negative keywords) have a "campaignCriterionStatus" field, and biddable adgroup criteria also have a "userStatus" field. However, shared criteria and negative adgroup criteria don't seem to have an equivalent field to indicate if the criterion has been removed.
I assume this means that the removed criteria just won't appear in the result of a query?
This means that to update my database, I need to query all criteria, and check which criterion in our database are not in the query result?
This of course is not very efficient, as those queries can yield large amount of results.
Any advice on this?
Thanks.
