Dialogflow, formerly known as Api.ai, is a natural language understanding platform that makes it easy to design and integrate a conversational user interface into your mobile app, web application, device, bot, interactive voice response system, and so on. Using Dialogflow, you can provide new and engaging ways for users to interact with your product.

With Dialogflow integrated with the IS-Messenger platform, you can:

  • Develop powerful conversational functionalities

  • Deliver messages on the requests of users

  • Store profile-specific information

  • Retain contextual awareness

Dialogflow Editions

Dialogflow offers two main types of agents: Dialogflow CX and Dialogflow ES.

  • Dialogflow CX is designed specifically for large-scale and complex conversational systems suitable for enterprises.

  • Dialogflow ES is a simpler edition that is well-suited for small to medium-sized businesses and organizations that are just starting out with chatbots and conversational systems.

FAQ and Troubleshooting

Why am I getting "The key could not be validated. Invalid key provided" error?

This error occurs because the API key generated from a non-global server is not supported by IS Messenger. Currently, IS Messenger only supports global Dialogflow agents.
