A Facebook Messenger Bot built with Node.js and the Google Cloud Dialogflow API. Based on natural conversational experiences with users seeking movie recommendations, the bot passes conversation entities to The Movie Database API and retreives movies for users.
A webhook service is designed to handle all received user messages, via Express routes, from the Facebook Messenger and Dialogflow APIs. The webhook passes off the Messenger request to the Dialogflow API, which interprets the conversation intents & entities. Finally, the resulting entities are queried using The Movie Database API and returned to the webhook, which sends generated responses back to Messenger.
