N8n

Overview

Connect your Telnyx Voice AI agent with n8n to trigger sophisticated automation workflows from any voice interaction. The integration allows agents to kick off multi-step workflows, update records across connected apps, and orchestrate complex business logic - all triggered by natural conversation. With n8n’s visual workflow builder, you can chain together hundreds of app nodes, conditional logic, and data transformations, turning every call into an actionable automation pipeline.

How it works

This video shows how a Voice AI agent built on Telnyx triggers an n8n workflow during a call. The agent captures intent from the conversation, sends a webhook to n8n, and n8n orchestrates the workflow across multiple connected services - updating records, sending notifications, and executing business logic in real time.

Capabilities

The n8n integration supports the following operations through HTTP Request nodes and webhooks:

Workflow Triggers

trigger_workflow

send_webhook

get_workflow_status

list_workflows

Data Operations

get_execution_data

update_workflow_data

list_executions

App Nodes

About n8n

n8n is an open-source workflow automation platform that lets technical teams build AI agents and integrations visually. With over 500 pre-built connectors and support for custom API calls, it enables teams to automate complex processes while keeping every step of an agent's reasoning traceable and controllable.

What moves between the agent and n8n

A Telnyx voice AI agent can trigger n8n workflows and pass data through API tool calls during a phone conversation. When a caller requests an action - like creating a ticket, updating a record, or running a data lookup - the agent can call an n8n webhook with the relevant parameters and relay the result back to the caller.

The agent can send structured data from the call into n8n workflows, including caller details, issue descriptions, and conversation context. n8n can then orchestrate multi-step automations across connected systems and return a response that the agent reads back to the caller.

For more complex setups, the agent can pass conversation context into n8n AI agent nodes that handle reasoning, RAG lookups, or multi-system data enrichment - letting the voice agent act as the front door to sophisticated backend automations.

COMPOSITION

Pick the job. The primitives light up.

Four n8n assistants. Pick one and the blocks it runs on light up, and the create call attaches n8n in the same request, the meter prices it. Or click any single block: every primitive sells alone.
