The Messenger customer chat plugin allows you to integrate your Messenger experience directly into your website. This allows your customers to interact with your business anytime with the same personalized, rich-media experience they get in Messenger.
The customer chat plugin automatically loads recent chat history between the person and your business, meaning recent interactions with your business on messenger.com, in the Messenger app, or in the customer chat plugin on your website will be visible. This helps create a single experience for your customers and enables you to continue the conversation even after they have left your webpage.
