Bots are the next big thing for messaging apps, and Facebook wants to make sure that it’s one of the first companies to implement them. During its annual developers conference on Tuesday, the company announced Bots for Messenger, a new API that will allow third parties to add their own chat bots to Facebook Messenger. There are numerous potential uses for this, but it’s business-to-customer interaction that Facebook is most interested in, and the company already has more than thirty partners taking advantage of this new API.
