Are negative placement comments available via API

[TJ]

When we manually add negative placements via AdWords Editor, our account managers commonly write comments about each negative placement. But when we add negative placements via API, this field "Comment" is undocumented in the API instructions. If "comment" is available in AdWords editor, it should be be accessible via API but we cannot figure out how to write a comment via the API. Is there a way to write comments for negative placements via API that is possibly not in the documentation?

Hi,

I am afraid that you won't be able to add comments in negative placements using AdWords API. Thanks for the feed back. I'll will let the team know about your request. Please keep an eye on our blog for any upcoming updates regarding this feature. 

Thanks,
Milind, AdWords API Team
