Universal Containers would like to route SMS text messages to a service rep from an Agentforce Service Agent. Which Service Channel should the company use in the flow to ensure it’s routed properly?

To route SMS text messages via Omni-Channel, a Service Channel must be configured for the MessagingSession object. Salesforce automatically creates a "Messaging" Service Channel when you set up a messaging channel (like SMS). This channel links incoming text messages to the Omni-Channel routing engine. An Omni-Channel flow then uses the Route Work action to direct these MessagingSession records to the appropriate agent, but the "Messaging" Service Channel is the foundational component that defines this type of work item for routing.

B. Route Work Action: This is an action within an Omni-Channel Flow that executes the routing logic. It is not the Service Channel itself, which defines the source object (e.g., MessagingSession) for the work.
C. Live Agent: This Service Channel is specifically for routing real-time web chats (represented by the LiveChatTranscript object), not for asynchronous SMS text messages.

1. Salesforce Help, "Create Service Channels": "A service channel lets you turn nearly any Salesforce object...into a work record. Omni-Channel then plucks these work records from their queues...and routes them to your agents... For channels like chat, messaging, and voice, service channels are created for you." This document confirms that "Messaging" is a distinct Service Channel type created automatically for channels like SMS.

2. Salesforce Help, "Route Messaging Sessions with Omni-Channel": "When you complete Messaging setup, a service channel and a basic routing configuration are created for you... The service channel controls the settings for the Messaging Session object." This source directly links the setup of SMS with the creation of a "Messaging" Service Channel for the MessagingSession object.

3. Salesforce Help, "Route Work with Omni-Channel Flows": This document details the Route Work action, describing it as the flow element that "routes a work item to a queue, agent, or skill." This distinguishes the action of routing from the definition of the work item, which is the role of the Service Channel.
