Why bot framework

Developers writing bots all face the same problems:

• Require I/O
• Lang and Dialog Skill

REST API

You can create a bot with any programming language by using the Bot Framework REST API. There are three REST APIs in the Bot Framework:.

• Bot Connector REST API : send and receive messages to channels configured in the Bot Framework Portal.
• Bot State REST API : enables your bot to store and retrieve state.
