Channels Connector

General description

Channels connector is a component responsible for providing a bridge between different channels and SentiOne Automate. It allows to conduct conversations with Automate bots. It's meant to replace separate "Bot" apps by merging them into one application.

List of supported channels is available here.

API

Default port: 5782

There are default endpoints for monitoring purposes. They are described in Components monitoring section.

Databases

The component reads and writes data to queues:

automate.webhooks.messenger - used for Facebook's webhooks
automate.webhooks.vonage - used for Vonage's webhooks
automate.webhooks.twilio - used for Twilio's webhooks
