n8n Troubleshooting and Validation

This section provides guidance to validate and troubleshoot your n8n integration with SailPoint Entro.

Management → Accounts & Integrations → Target Service filter → n8n

Validation Steps

Confirm connection status

In the SailPoint Entro Dashboard, navigate to Management → Accounts & Integrations → n8n and confirm the integration status shows Verified.
Review Inventory

Navigate to AI Inventory and filter by n8n. Confirm that workflows appear and ownership is attributed to n8n users.
Confirm AI agent detection

Confirm that workflows containing LLM nodes (LangChain, OpenAI, Anthropic, Google Gemini) are categorized as AI Agents.

Use the following commands to manually verify that your API key and instance URL are working correctly before connecting in SailPoint Entro.

curl - validate user access

curl -X GET "https://<your-instance-url>/api/v1/users" \
     -H "X-N8N-API-KEY: <your-api-key>"

curl - validate workflow access

curl -X GET "https://<your-instance-url>/api/v1/workflows" \
     -H "X-N8N-API-KEY: <your-api-key>"

Expected response: a JSON object listing users or workflows accessible with your API key.

Issue	Cause	Resolution
401 Unauthorized	Invalid or expired API key	Re-generate the API key in n8n and update the integration in SailPoint Entro
Connection timeout	Firewall blocking outbound traffic	Allow outbound HTTPS (port 443) to your n8n instance
Missing AI workflows	Unsupported or unrecognized node types	Verify workflows use supported LLM nodes — see Permissions Reference
No workflows visible	Incorrect Base URL format	Ensure the Instance URL does not end with `/api/v1`
