How do I connect Slack (legacy)?

Sign up for Conductor Deck, then add a Slack (legacy) step to a workflow on the visual canvas. The builder walks you through the connection it needs — an account authorization or the required keys — right inside the step. No separate setup or code.

Yes — Conductor Deck has a free tier you can build and run workflows on, with no credit card required. Paid plans raise the monthly run limits and add advanced features when you need them.

What's the difference between a trigger and an action?

A trigger is the event that starts a workflow — for example, a Stream Deck button press or an incoming event from a connected app. An action is a step the workflow performs once it runs. A workflow is one trigger followed by one or more actions.
