Flex Chat Channel Resource

(information)

Info

This guide is for Flex UI 1.x.x and channels that use Programmable Chat and Proxy. Programmable Chat for Flex will reach end of life on June 1, 2026. If you're new to Flex or currently using Programmable Chat, build with Flex Conversations or migrate.

Flex Chat Channels allow agents to communicate with your customers across multiple channels like Webchat, SMS, and WhatsApp through a single chat interface. You can create a chat channel in Flex whenever you want to initiate a new communication flow between an agent and a customer. The Flex Chat Channel is an implementation of the Chat Channel Resource orchestrated for Flex.
