Slack is a **two-way** channel: your apps can post into Slack channels, and they can react when someone sends a message, mentions your bot, adds a reaction, or clicks a button. You connect a workspace in your dashboard, then describe what you want and the agent builds it. ```mermaid theme={null} flowchart LR User["👤 Someone in Slack"] -- "message / mention / click" --> SD["☁️ Stardeck"] SD -- "forwards to your app" --> App["📱 Your app"] App -- "post message" --> SD SD -- "delivers to Slack" --> User ``` Your app never holds the Slack bot token—Stardeck brokers every call. See [Connected Services](/connected-services/overview) for the shared model. ## What you can build Describe what you want in the project chat. Some examples: **Send notifications to a channel** ``` Post a message to our #orders channel whenever a new order comes in ``` **Send rich, interactive messages** ``` When a refund is requested, post it to #support with Approve and Deny buttons ``` **React to messages and mentions** ``` When someone @mentions our bot in Slack, look up the order they name and reply in the thread ``` **Run approval flows** ``` When a manager clicks Approve in Slack, mark the refund approved and notify the customer ``` You describe the outcome—the agent designs the flow and wires it up. See [Receiving events](/connected-services/slack/receiving-events) for how messages and clicks reach your app. ## Next steps Add a Slack workspace and grant it to your apps React to messages, mentions, and button clicks How linked accounts work across the platform Message customers on LINE too
