Channels Overview

OmniBots supports deploying your bots across multiple communication channels. Each channel connects to the same published bot, so your conversation logic is defined once and delivered everywhere.

Channel Architecture

All channels connect to the same OmniBots orchestrator:

Orchestrator Service (WebSocket or REST)

Channel architecture: device to adapter to orchestrator

Each channel adapter translates between the channel-specific message format and the internal OmniBots message schema. This means:

• A single bot flow serves all channels
• Channel-specific content (e.g., voice prompts vs text) is handled by node configuration
• Session state is shared if a user switches channels mid-conversation

TIP

Design your flows with channel awareness in mind. The {{sys_channel}} system variable is available in conditions so you can branch logic for voice vs text interactions.

Enabling a Channel

1. Go to Settings > Integrations and add the relevant provider credentials
2. Navigate to your bot's Channels tab
3. Select the channel and configure channel-specific settings
