I am new to Google Ads API. I know there should be a way to add multiple keywords to a keyword plan within a single API call. I have about 2000 keywords so I don't want to waste my daily operations on just adding them to the plan. I read through the batch processing, but none of the
MutateOperations seem to have keyword related features. Which specific API operations should I call to add multiple keywords to a keyword plan? If it can't be done within one call, what particular method I should use to combine or reduce calls?
Thank you.
