Software engineer Nitin Garg detailed all the updates to Facebook’s flagship messaging app in a blog post.

Brands with multiple apps connected to Messenger Platform can now easily select which one of their apps to use in their click-to-Messenger ads.

Brands can also set icebreakers in their Messenger profiles via the API, enabling them to reduce friction when starting conversations by surfacing common questions or topics of interest.

Finally, the update gives brands the ability to see people’s reactions to their messages, with Garg writing, “Message replies adds context to a conversation. Businesses can see which message the user is responding to. This adds more clarity to the conversations and helps businesses respond to inquiries better.”
