Is ID in CAMPAIGN_NEGATIVE_KEYWORD unique globally?

[Oliver]

We know that regular keywords IDs are unique only within their adgroups.

1) What about the IDs of negative keywords at the campaign level (retrieved via the CAMPAIGN_NEGATIVE_KEYWORD_PERFORMANCE report)?  Are they unique globally?

2) What about the IDs of negative keywords in shared lists that are retrieved via the SHARED_LIST_CRITERIA report?  Are they unique globally?

Hi Oliver, 

Please see AdWords API Objects guide. CampaignCriteriaIDs are not globally unique. The combination of campaignId and CriteriaId are unique. 

Thanks,
