Update message - Automate.ax

slack.updateMessage changes a bot-authored message. Slack doesn’t let the bot edit messages posted by other users or apps.

Example

automations/update-slack-message.automation.ts

import { automation } from "automate.ax"
import { slack } from "automate.ax/slack"

export default automation("Update Slack status", () => {
  slack.updateMessage({
    conversationId: "C01234567",
    timestamp: "1700000000.000001",
    text: "Deployment finished.",
  })
})

Inputs

Input	Type	Required	Description
`conversationId`	`string`	Yes	Conversation containing the message.
`timestamp`	`string`	Yes	Timestamp identifying the message.
`text`, `blocks`, `attachments`	Slack message content	At least one	Replacement content. Blocks have a maximum of 50, and attachments have a maximum of 100.
`unfurlLinks`, `unfurlMedia`	`boolean`	No	Slack unfurl behavior.
Second argument: `{ account }`	`string \| IntegrationAccountReference<"slack">`	No	Slack binding. Defaults to the project binding.

Output

Returns the message’s conversationId, timestamp, and message. Supplying text without blocks removes existing blocks. Pass an empty blocks array when you intentionally want to clear blocks while retaining other content.
