n8n LinkedIn automationLinkedIn outreach inside your n8n workflows.

What you can build

• Form or CRM to LinkedIn. A new signup, a Google Sheets row or a CRM stage change enrolls the person in a LinkedIn sequence.
• Reply routing. Interested replies go to Slack, your CRM or a task tool, with the conversation attached.
• AI triage with a human check. Draft a response with an LLM node, then queue it in SalesMix Approvals instead of sending it blind.
• Ops alerts. Get notified when an account hits its daily limit with account.limit_reached.

Step 1: Store your API key as an n8n credential

Create an API key in SalesMix, then add a Header Auth credential in n8n with the name Authorization and the value Bearer YOUR_KEY. Every HTTP Request node can reuse it.

Step 2: Enroll leads with the HTTP Request node

Add an HTTP Request node after whatever produces your leads. Set the method to POST and the URL to your sequence's leads endpoint. Turn on "Send Body" with JSON and map fields with n8n expressions.

// URL
https://api.salesmix.com/v1/sequences/seq_8Fk2/leads

// Headers (Authorization comes from the credential)
Idempotency-Key: {{ $json.id }}

// JSON body
{ "leads": [{
    "linkedin_url": "{{ $json.linkedin_url }}",
    "first_name": "{{ $json.first_name }}",
    "company": "{{ $json.company }}",
    "custom": { "source": "{{ $json.source }}" }
  }] }

// → 202 Accepted
{ "enrolled": 1, "skipped_duplicates": 0 }

Fields inside custom become message variables, so source is available as {{source}} in your sequence. The same node pattern works for any other endpoint on the API reference, such as pausing a sequence or replying to a conversation.

Step 3: Receive SalesMix events with the Webhook node

Add a Webhook node as the trigger of a new workflow, set it to accept POST, and copy its production URL. Then subscribe that URL to the events you care about with one API call (you can make it from another HTTP Request node).

{
  "url": "https://your-n8n-host/webhook/salesmix-replies",
  "events": ["message.replied", "connection.accepted"]
}

Each event is a signed POST with the lead, account, sequence and step attached, and replies include an intent label. Add an IF node on the intent to route interested replies one way and everything else another.

Useful SalesMix events for n8n

The full list is on the webhooks section of the API page. Prefer working with AI agents directly? The SalesMix MCP server gives Claude or Cursor the same actions, with approvals.

Before you scale an n8n workflow

Automations make it easy to enroll thousands of leads at once. That's fine: SalesMix queues them and sends from each account at its own safe daily pace, spread across your connected accounts. If you need more volume, add accounts rather than pushing one harder. Starter covers up to 5 accounts for $99/mo, and Unlimited has no cap. See pricing.
