Rasa

The Rasa app facilitates the integration of your Rasa bot with Rocket.Chat, enabling you to handle conversations from multiple channels through a single Rasa bot.

{% hint style="info" %} To set up your Rasa server, visit the Rasa installation guide. {% endhint %}

Rasa app operation modes

The Rasa app operates in two modes: Synchronous and Asynchronous modes.

Synchronous Mode

The app utilizes Rasa's REST API to exchange messages in synchronous mode. To enable this mode, configure the Rasa bot's credentials.yml file and enable the REST API.

Asynchronous / Callback Mode

In asynchronous mode, the app utilizes callbacks to receive messages from Rasa. It is helpful if your app uses features like Reminders and External events, as they only work in this mode. To configure Rasa for this mode, you need to include the following configuration in the credentials.yml file of your Rasa server:

callback:
  url: "<your-callback-url"

{% hint style="info" %} To get your app callback URL, navigate to the Rasa App Info > Details > APIs on your workspace**.** {% endhint %}

Install Rasa App

It's recommended to install the Rasa app from Rocket.Chat marketplace.
