I'm looking to implement a feature to automatically apply account labels to client accounts. While the basic feature works, I have a few questions about scalability.
The Ad Words API
docs clearly state that one label can only be added to 1000 accounts at most, a limitation we'd hit rather soon. The Google Ads API equivalent,
CustomerLabelService, does not seem to have such a limitation, or at least it's not documented.
So, my questions:
1) Is the 1000-accounts-per-label limitation actually in place for both Ad Words and Google Ads APIs?
2) If so, is there any way -- with either API -- to check how many accounts any one label has been attached to?
Cheers,
Mark
