Installation

Follow the installation guide in the n8n community nodes documentation, and search for @biztory/n8n-nodes-autom8-tableau-alert-trigger.

Authentication

This node authenticates using a Tableau Connected App (Direct Trust). Connected Apps let a service account sign JWT tokens instead of using a stored password.

1. Create a Connected App in Tableau

1. In Tableau Cloud or Tableau Server, go to Settings → Connected Apps.
2. Click New Connected App → Direct Trust.
3. Give it a name (e.g. n8n integration) and click Save.
4. Open the Connected App and click Generate New Secret.
5. Copy and store the Client ID, Secret ID, and Secret Value — the secret value is only shown once.

2. Configure the credential in n8n

Add a new Autom8 Tableau Connected App credential and fill in the following fields:

| Field | Description | |---|---| | Server URL | Base URL of your Tableau instance, e.g. https://prod-useast1.online.tableau.com | | Site Content URL | The site name that appears in your Tableau URLs. Leave empty for the Default site. | | API Version | Tableau REST API version, e.g. 3.23. Check your Tableau release notes for the supported version. | | Client ID | From the Connected App overview page. | | Secret ID | From the generated secret. | | Secret Value | From the generated secret (shown only at creation time). | | Username | The Tableau username (email) the node will impersonate when querying data. | | Scopes | Space-separated JWT scopes. Use tableau:views:download for the View source, tableau:viz_data_service:read for the Datasource source, or both. |

Usage

1. Add the Autom8 Tableau - Data Alert Trigger node to a new workflow.
2. Select the credential you created above.
3. Pick a Source (View or Datasource) and a Condition (Any Rows Returned or Row Count Threshold).
4. The node polls on n8n's configured polling interval and emits items whenever the condition is met.

Finding a View ID or Datasource ID

The View ID and Datasource ID fields expect the object's LUID — the UUID-style identifier visible in the Tableau REST API and in the object's URL on Tableau Server/Cloud.

Example: alert when open support tickets exceed a threshold

Scenario: A Tableau view is pre-filtered to show only open support tickets. The workflow should fire and post a Slack message whenever that count exceeds 50.

Trigger node configuration:

| Setting | Value | |---|---| | Source | View | | View ID | (LUID of your "Open Tickets" view) | | Condition | Row Count Threshold | | Operator | > (Greater Than) | | Threshold | 50 | | Emit | Single Summary Item |

The trigger emits one item with the shape:

{
  "row_count": 63,
  "triggered_at": "2025-06-01T09:15:00.000Z",
  "source": "view",
  "rows": [ ... ]
}

Connect a Slack node after the trigger and reference {{ $json.row_count }} in the message body:

⚠️ 63 open support tickets — threshold of 50 exceeded. [View in Tableau →]

Compatibility

Tested and supported starting with n8n version 2.18.5.
