Flex Messaging Limits
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.
Rate limits on API endpoints
Rate limits return HTTP 429 when exceeded and should be handled accordingly on the customer side.
