Slack Slash Command

trigger/slack-slash-command — Trigger workflow when someone runs a Slack slash command.

Where it appears

The Slack Slash Command block is a trigger — it starts a workflow. Add it from the Triggers group in the Workflow Builder.

Field	Type	Required	Default	Description
`webhookUrl`	text	No	—	Paste this into the Request URL of your slash command (Slack app settings → Slash Commands). The Slack connection above must hold that app's Signing Secret.
`ackMessage`	text	No	`Working on it…`	Shown right away, only to the person who ran the command, while the workflow runs. Leave blank to acknowledge silently. Use a Reply to Slack Command step to send the result.
`testInput`	code	No	—	Sample slash-command fields to use when running this workflow in test mode instead of waiting for a real command.

Inputs are the configurable fields above. The block produces these outputs:

Outputs

Reference an output downstream with <Slack Slash Command.field>.

`text`	string	Everything the user typed after the command
`user_id`	string	Slack ID of the user who ran it
`channel_id`	string	Slack ID of the channel it was run in
`team_id`	string	Slack workspace ID
`enterprise_id`	string	Enterprise Grid org ID, when the workspace belongs to one

A minimal configuration for this block:

{
  "type": "trigger/slack-slash-command",
  "config": {
    "ackMessage": "Working on it…"
  }
}

Requires a connected Slack integration. Calls fail if that integration is disconnected or its authorization has expired.
