Dialogflow Fulfillment Library

The Dialogflow Fulfillment Library makes creating fulfillment for Dialogflow v1 and v2 agents for 8 chat and voice platforms on Node.js easy and simple. Cross-platform text, card, image, suggestion are supported for Actions on Google, Facebook, Slack, Telegram, Kik, Skype, Line, Viber and Dialogflow's simulator with custom payload support for all platforms.

Dialogflow fulfillment allows you to connect Dialogflow's natural language understanding and processing to your own systems, APIs and databases. Using fulfillment, you can surface commands and information from your services to your users through a natural conversational interface.
