# Slack

> Read conversations, send messages, upload files, and react to Slack events from TypeScript automations.

Import Slack actions and triggers from `automate.ax/slack`. Actions accept plain
values or compatible signals; triggers return signals containing normalized
Slack event data.

```ts theme={null}
import { automation } from "automate.ax"
import { onAppMention, replyToThread } from "automate.ax/slack"

export default automation("Answer Slack mentions", () => {
  const mention = onAppMention()

  replyToThread({
    conversation: mention.conversationId,
    text: "Thanks — I’m looking into it.",
    threadTimestamp: mention.message.timestamp,
  })
})
```

## Accounts

Leave `account` unset to use the project's default Slack binding, or pass a
binding for another workspace. See [Integration accounts](/concepts/integration-accounts).
Trigger account selection must be static.

Slack uses opaque conversation IDs and message timestamps as identifiers. Keep
the `conversationId` and `timestamp` returned by message actions and triggers;
follow-up actions usually need both.
