How to validate/test the Google My Business APIs with more than 200 locations?

I am a backend developer in a SaaS startup. I wish to test all possible responses from the exposed Google My Business APIs. I have set up a test account with 2 locations, however, I would like to test for 200 or more locations. I am wondering how others tested their code while developing their product using Google My Business APIs. (I would like to test scenarios like fetching more than 100 locations associated to a single account)
