Flex Messaging Limits


(information)

Info

This guide is for Flex UI 1.x and channels that use Programmable Chat and Proxy. If you are using Flex UI 2.x or you are starting out, we recommend that you build with Flex Conversations.

Due to various limitations and concerns, Flex messaging orchestration will constrain certain actions.
