Disclosed are some implementations of systems, apparatus, methods and computer program products for publisher and share action integration in a user interface (UI) for automated messaging. In some implementations, information is displayed in a first component and in a second component in a UI on a display. The first component is a publisher configured for composing and sharing messages on different communication channels using different share actions. The second component includes links to data items. When one of the data items is selected, a set of share actions for sharing the selected item using the publisher can be identified and displayed. When one of the displayed share actions is selected, it can be determined that the selected share action is applicable to one of the communication channels. A reference to the selected item can be provided in a message being composed in the publisher for sharing on the one communication channel.
