About Facebook Messenger
Facebook Messenger is a messaging app and platform. Users can send messages and exchange photos, videos, stickers, audio, and other files. This app on Zapier works for conversations that are sent to and from Facebook pages and does not yet support direct messages to a user.
Slack is a platform for team communication: everything in one place, instantly searchable, available wherever you go. Offering instant messaging, document sharing and knowledge search for modern teams.
