Outlook integration with PHP based app

[direselign]

I have written a PHP api that connects to a Microsoft account to add appointments to a calendar. For first time use, the user is required to authenticate with username and password before a token is issued. Is there a way to bypass internally with PHP (passing a username and password) without prompting the user to do so?
