Hi,
I replied to you directly last week from this address. Perhaps check your spam folder to see if my message wound up there.
Here's a version of my response without your account specifics.
Our
labels guide mentions that for
applied_labels:
The "customer making the API call" there refers to the
login-customer-id specified on the request. I see that in the requests in your logs, you are specifying a
login-customer-id of
A, which is the parent manager of
B. Since
A does not
own the labels you mentioned, the response will not include them. However, if you change the
login-customer-id to
B, the labels should be returned in the
applied_labels collection. Note that youwill only be able to change the
login-customer-id to
B if you have OAuth credentials for a user who has
direct access to
B.
Hope that helps! Please let me know if you have any remaining questions.
Cheers,
Josh, Google Ads API Team
