## Chatbot API

Chatbot API allows the connection of any chatbot. The connection is done by registering a webhook to which events are sent. A chatbot is added by inserting your webhook to send events in the [Chatbots](https://docs.mluvii.com/en/for-administrators/tenant-management/settings/chatbots) section.

## Microsoft Bot Framework

The connection is done using the [Microsoft Direct Line](https://docs.microsoft.com/en-us/azure/bot-service/bot-service-channel-directline?view=azure-bot-service-4.0) API WebSocket. A chatbot is added by inserting a secret in the [Chatbots](https://docs.mluvii.com/en/for-administrators/tenant-management/settings/chatbots) section.

## Supported activities

Most activities are common to both types of chatbots. Chatbot API differs only in the need to specify SessionId in the activity.
