Configuration
3 fields, 2 required. A dotted path is a nested object and name[] an array of objects — the editor renders the same tree.
| Field | Type | Required | Default | Constraints | Example |
|---|---|---|---|---|---|
user_id The user id (U…) whose App Home tab to publish. Supports {{ }}. | string | Yes | — | — | — |
view The Block Kit view payload as a JSON object, with type, title and blocks. | object | Yes | — | ≥ 1 characters | — |
hash The hash of the view being replaced, to lose a race rather than clobber it. | string | No | — | — | — |
Output
One shape.
result
| Field | Type | Example |
|---|---|---|
ok Always true; a failure raises instead. | boolean | true |
view_id Slack's id for the view that was opened or published. | string | — |
hash The view's version hash — pass it back to guard an update. | string | — |
view The whole view object Slack returned, unmodified. | object | — |
{
"hash": "",
"ok": true,
"view": {},
"view_id": ""
}Notes
- The bot must be a member of a private channel before it can act there (Slack answers not_in_channel otherwise).
- Slack rate-limits each Web API method on its own tier; a throttled call fails with the number of seconds to wait and is safe for the node's retry policy to repeat.
- The view type must be home, and the app must have the App Home tab enabled.
Templates that use Slack
See Publish Home Tab run in a workflow.
In a technical demo we add the Slack connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
