Google Contacts API vs People API

Question

I\'m having a problem with the 2 APIs above. Given the next scenario: I have 2 different google accounts. One that doesn\'t use Google+ and a second account that uses Google

Answer 1

I found the difference between the 2 APIs and it has nothing to do with the fact that one of the accounts is connected to Google+ or not

People API will only fetch the contacts that are under the account "My contacts" contacts, while Contacts API will also fetch the other contacts lists ("Other contacts", "Most contacts", ...)
