I'm using the Marketing Solutions Criteo API.
I want to withdraw metrics at Ads level, but there is no endpoint for ads, and the lowest level available seems to be Adsets.
Therefore, I'm using the endpoint statistics/report in analytics to get information on Ads level, given that there is an AdId and Ad (ad name): https://developers.criteo.com/marketing-solutions/docs/campaign-statistics
The response includes a total, and rows. I expected these rows to be at Ad level, but it's not clear to me what are these rows. For example, If I receive a 115 rows response, 28 of them have as AdId an empty string, other 28 of them have -1 as AdId and a number also repeated 28 times as another AdId, then there are just a few unique values. What is the API actually returning me on rows? It doesn't seem to be Ads, then what is it?
I cannot find anything on these rows in the documentation.
