How to connect n8n to LinkedIn, step by step

What you need

• A Finchreach account (sign in at finchreach.com) and the LinkedIn account you want n8n to work on.
• n8n (self-hosted and Cloud. Older versions of the node only speak SSE: update n8n).
• About five minutes.

Step 1: Create a Finchreach API key

1. Sign in at finchreach.com and open API keys.
2. Create a key and name it after the tool, for example “n8n”.
3. Copy it right away: it starts with lk_ and is shown only once.

Step 2: Connect your LinkedIn account

1. Open Accounts and click to connect LinkedIn.
2. Follow the steps until the account shows as connected.

Approval mode is on by default: nothing the assistant drafts reaches LinkedIn until you approve it.

Step 3: Add Finchreach to n8n

1. In a workflow, open the AI Agent node → Tools → + → MCP Client Tool.
2. Endpoint URL https://mcp.finchreach.com/mcp, transport HTTP Streamable.
3. Authentication: Bearer Auth with the token lk_YOUR_KEY, or Header Auth with name Authorization and value Bearer lk_YOUR_KEY.
4. Under Tools to Include, pick all tools or just the ones the workflow needs.

{
  "name": "Authorization",
  "value": "Bearer lk_YOUR_KEY"
}

Replace lk_YOUR_KEY with your key. Keep the key out of shared files and repos; where n8n can read it from an environment variable, prefer that.

Bearer, Header, Multiple Headers and OAuth2 are supported.

Requirements: Self-hosted and Cloud. Older versions of the node only speak SSE: update n8n.

Step 4: Test the connection

In n8n, start with a read. It runs right away and proves the key and the account work:

Ask your assistant“List my connected LinkedIn accounts, then summarize my five latest notifications.”

You should see calls to linkedin_list_accounts and linkedin_get_notifications. Then try a write, which goes to your approval queue instead of LinkedIn:

Ask your assistant“Draft a short LinkedIn post saying I’m trying a new AI assistant workflow. Submit it for my approval.”

Step 5: Approve or reject it in Finchreach

1. Open Approvals. The draft is there with its exact text and the account it would go out from.
2. Approve it to publish, or reject it (reject the test post if you don’t want it live).
3. n8n can check the result with linkedin_get_action: pending, approved, rejected, executed, failed or expired.

Troubleshooting

• No HTTP Streamable option means your n8n is too old for Finchreach; update it.
• Limit Tools to Include to what the workflow needs, so the agent can’t draft writes you didn’t plan for.
• 401 or “unauthorized”: the key is wrong, revoked or missing its prefix. Finchreach accepts Authorization: Bearer lk_… or X-API-Key: lk_…; check for a missing Bearer , quotes or a trailing space.
• A tool is missing: the key’s permissions don’t include it. Create a key with the permissions you need under API keys.
• “No LinkedIn account”: connect one under Accounts, or reconnect it if its session expired.
• A post or message “didn’t go out”: it is probably still waiting under Approvals. Writes run only after you approve them.

Still stuck? Compare your setup with n8n’s documentation, checked on 2026-10-28; client screens change often.

What to ask n8n next

Ask your assistant“When a new row lands in the leads sheet, find the person on LinkedIn and draft an invitation with a note.”

Ask your assistant“Every morning, summarize new LinkedIn messages and send the summary to Slack.”

Ask your assistant“When we publish a release on GitHub, draft a LinkedIn post about it.”
