Connecting Google account as outgoing email account
LiveAgent uses Google OAuth authentication to connect with your Gmail accounts. After you authenticate this connection in a pop-up window, your Gmail mailbox is connected, and no further configuration is needed. Just follow these simple steps:
In your LiveAgent account, navigate to Configuration > Email > Outgoing Mail accounts, and click on the "Integrate new email account" button.
In the left "Mailbox account" section, use the Google connector to connect your Gmail account.
