n8n - Trikon Voice

n8n is a workflow tool (self-hosted or cloud). Use an HTTP Request node to call Trikon, and a Webhook node if you want call results back in the same workflow. The existing API overview already calls out n8n as a way to trigger reminder calls from a CRM or form.

Before you start

n8n instance you control (so the API key is not shared with a public template).
Trikon API key, workspace slug, outbound agent ID, and phone-line UUID.

Store the API key as a credential

In n8n, create a Header Auth credential:

Field	Value
Name	`Authorization`
Value	`Bearer YOUR_API_KEY`

Use that credential on every HTTP Request node that talks to Trikon. Do not put the key in a Set node that gets logged.

Start an outbound call

Trigger

Use whatever starts the flow — Webhook (form submit), Schedule, Google Sheets, HubSpot, etc. Map a phone number in E.164 (+91…).

HTTP Request

Method: POST
URL: https://voice.trikon.tech/api/outbound-call
Authentication: the Header Auth credential above
Content type: JSON
Body:

{
  "to": "{{ $json.phone }}",
  "agentId": "8f2c1d34-5b6a-4c7e-9f10-2a3b4c5d6e7f",
  "enterprise": "acmeclinic",
  "from": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
  "name": "{{ $json.name }}",
  "metadata": {
    "amount_due": "{{ $json.amount_due }}",
    "due_date": "{{ $json.due_date }}"
  }
}

Save the call id

The response includes success and callUuid. Write callUuid back to your sheet or CRM so you can match the later webhook.

Field reference: Make a call.

Create a lead, then call it

If you want the contact to appear in Leads first:

POST https://voice.trikon.tech/api/developer/leads with JSON:

{
  "enterprise": "acmeclinic",
  "agentId": "8f2c1d34-5b6a-4c7e-9f10-2a3b4c5d6e7f",
  "name": "{{ $json.name }}",
  "phone": "{{ $json.phone }}",
  "notes": "{{ $json.notes }}",
  "source": "n8n"
}

A 201 response includes lead.id.

Optionally POST https://voice.trikon.tech/api/developer/leads/{{ $json.lead.id }}/call with the same Bearer header to ring that lead immediately.

Phone can also be sent as phone_number or mobile — the developer leads endpoint accepts several aliases.

Receive post-call events

Add a Webhook node

Create a workflow with a Webhook trigger, method POST, path e.g. trikon-call. Copy the production URL.

Paste it into Trikon

Settings → Developer API → Call webhook.

Respond immediately

Set the Webhook node to respond with 200 as soon as the body is received. n8n should not wait on CRM updates — Trikon retries if you take longer than about 3 seconds.

Branch on event

Switch on {{ $json.event }}: call.completed, call.no_answer, call.failed, recording.ready, analysis.completed. Use intent and summary when analysis.completed arrives.

Payload details: Webhooks.

Trigger n8n Workflows Live During Phone Calls

You can also have your AI Voice Agent trigger an n8n webhook in the middle of a live voice call to fetch or submit data (e.g. checking CRM records or triggering instant WhatsApp notifications while speaking with the caller).

In n8n, create a Webhook node (POST).
In Trikon Voice, open your agent and go to Custom Tools.
Click Add Custom Tool, set Method to POST, and paste your n8n webhook URL.
Add parameters (e.g. customer_name, intent, phone_number).
When the caller speaks, the AI will call your n8n workflow in real time, receive the response, and speak it naturally!

See full guide: Custom Tools & APIs.

Test with your own phone in n8n’s manual execution first. When success is true, the row should show up in Call Logs within a few seconds of the call ending.
