Hi Brett,
Thanks for reaching out about this! We don't currently have a way to automate the keyword tracking data collection process and the data must be pulled manually.
I know that we have a lot of ideas for the future of our keyword tracking and an API is definitely on our wish list, but I'm not sure whether this would be used for campaign-like tracking. I'll make sure to bring this up with the Moz Pro product team again as something that would definitely be appreciated by our customers.
There is also survey you can take to register your interest in a keyword API and tell us what kinds of things you're looking for: https://www.surveymonkey.com/r/YZ58JVH
