## Overview

Post to Slack from a workflow and handle what happens there. Post messages and replies, post messages with buttons and act on the click, update and delete messages, react, open DMs, and look up people and channels. Every message, mention, reaction, new member, new channel and button click reaches one handler workflow, in a branch for its kind with typed values. Messages from bots are left out, so a workflow that posts never answers itself. Sign in with Slack and paste the app's signing secret after install. These calls cannot run inside a transaction.
