Open direct message - Automate.ax

openDirectMessage resolves the DM conversation for one Slack member. Use it before sending a direct message when you only have the person’s Slack user ID.

Example

automations/open-slack-dm.automation.ts

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

export default automation("Open Slack DM", () => {
  openDirectMessage({ userId: "U01234567" })
})

Inputs

Input	Type	Required	Default	Description
`userId`	`string`	Yes	—	Slack user ID of the other participant.
`preventCreation`	`boolean`	No	`false`	Fails rather than creating a DM when none exists.
`account`	`string \| IntegrationAccountReference<"slack">`	No	Project default	Slack workspace binding.

Output

Returns { alreadyOpen: boolean; conversation: SlackConversation }. Pass conversation.id to sendMessage. With preventCreation, Slack can reject the request if the two users have no existing DM.
