I’m trying to create an application that uses Google OAuth for login, and then scans through the users email to see the last time they emailing certain people.
So the user logs in with Google OAuth, and then inputs johndoe@gmail.com –> I want to be able to search through their gmail to tell them the last time they spoke.
I can get “feeds” of their inbox, and other folders, but I can’t find a way to query for an email.
Yes you can access a user’s mail with OAuth and the IMAP protocol. There is specifications on how to use the OAuth and IMAP combination on developers.google.com, check the links from here: https://developers.google.com/google-apps/gmail/oauth_overview
PHP has good support for the IMAP protocol: http://php.net/manual/en/book.imap.php
You can use imap_search() in PHP for searching for messages with IMAP: http://www.php.net/manual/en/function.imap-search.php
Edit: Sorry, the PHP IMAP support does not work with OAuth. You should use the Zend_Mail_Protocol_Imap, which has the functionality to authorize with an IMAP server using OAuth. Using the method
requestAndResponse, it is possible to make an IMAP SEARCH request.
