I am using the Google APIs Gmail in PHP to pull emails from my inbox and display them in my webapp. My problem is : Hangouts are pulled as well. I would like to pull only emails. I wanted to filter them by Labels but apparently Hangouts are labelled "INBOX" as well.
What can I do to pull only emails and avoid Hangouts ?
Use the "q" parameter when listing the user's messages and specify "!in:chats" along with any other filters you may need.
