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 â Connected Apps.
2. Click New Connected App â 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 â 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:vizdataservice: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 â 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:
> â ī¸ 63 open support tickets â threshold of 50 exceeded. [View in Tableau â]
Compatibility
Tested and supported starting with n8n version 2.18.5.
