Create keyword label via Google Ads API

Question

does anybody know if there is a way how to create a label for a keyword using Google Ads API? It can be done using the web interface and apparently it could be done using the Adwords API, but I can't find a way how to do it using Google Ads API so I don't know if it's a feature which they didn't implement or if I'm blind.

Their documentation says

Labels allow you to categorize your campaigns, ad groups, ads, and keywords, and use those categories to simplify your workflow in a variety of ways.

which would suggest that it CAN be done, however below on the same page it states

You can assign labels to your campaigns, customers, ad groups, criteria, or ads.

No word about keywords. I am working with PHP / Laravel and I am using their official php package for the API communication. The package has classes like CampaignLabelOperation, CustomerLabelOperation, AdGroupLabelOperation, etc. but NO "KeywordLabelOperation".

Anybody have a clue if I just can't find it or whatever I could do? Thanks a lot for any help

Answer 1

Technically speaking, Keywords are Ad Group Criteria . Therefore, you'd need to use the AdGroupCriterionLabelService 's MutateAdGroupCriterionLabels to create a keyword label.
