Adwords API for Keyword Research only

Looking for advice on the best way to implement the KEYWORD research portion of the adwords api.

This is not for running ads, just hitting their api and finding what related keywords there are and their search volume.

Related documentation here:
https://developers.google.com/adwords/api/docs/guides/targeting-idea-service#use_case

I'm going crosseyed figuring out just getting this Library/API usable in Unity

 

This doesn't look like something a group of game devs would have a lot of experience implementing. I'd guess google would have their own support forum though, which you might have better luck with.

 

yaw couldnt find anything, so calling the semrush api since its wayyy easier and pulls from adwords keywords planner anyway
