Self-hosted workflow automation for your voice agents
Connect AgentVoice to n8n and build powerful automation workflows that you own and control. n8n’s open-source, self-hostable architecture means your call data never leaves your infrastructure — while still giving you visual workflow building, 400+ app integrations, and the ability to drop into JavaScript or Python when you need custom logic.
For teams that need more control than SaaS automation tools provide, n8n is the answer. Self-host it on your own servers for complete data sovereignty, write custom code nodes when pre-built integrations aren’t enough, and build workflows as complex as your business requires. Your voice agent events trigger n8n workflows via webhooks, and from there you have full control over what happens next.
What your agent can do
During the call
- Trigger Workflows via Webhook — Fire webhook events to your n8n instance during the call to kick off workflows that query databases, call APIs, or notify team members in real time.
- Custom Code Nodes — Use JavaScript or Python nodes within your n8n workflow to transform, validate, or enrich call data with custom logic before returning it to your agent.
- Query Any API — n8n’s HTTP Request node lets you connect to any system with a REST API during the call — internal databases, proprietary tools, or legacy systems that don’t have pre-built integrations.
After the call
- Complex Workflow Logic — Build workflows with conditional branches, loops, merge nodes, and error handlers to route call data through sophisticated business logic.
- 400+ App Integrations — Connect call outcomes to CRMs, databases, messaging platforms, project management tools, and more through n8n’s built-in nodes.
- Data Sovereignty — Self-host n8n so call transcripts, customer data, and business logic stay on your infrastructure — critical for regulated industries.
- Version Control — Store your workflows in Git, manage them across environments, and deploy changes with the same rigor you apply to your codebase.
Use Cases
Healthcare Call Processing
- Voice agent handles patient calls and fires webhooks to a self-hosted n8n instance — patient data never touches third-party servers
- n8n workflow queries the EHR system via API, verifies patient identity, and returns appointment availability to the agent
- After the call, the workflow creates appointment records, sends HIPAA-compliant confirmations, and updates the patient’s chart — all within your private infrastructure
Custom CRM Workflows
- Call data hits n8n, where a JavaScript node scores the lead using your proprietary algorithm against your internal database
- Based on the score, the workflow branches — creating records in different systems, triggering different follow-up sequences, and assigning to different teams
- Custom code nodes enrich the data with information from your data warehouse before it reaches any destination system
Legacy System Integration
- Your voice agent needs to read and write data to a legacy system that only exposes a SOAP API or custom database protocol
- n8n’s HTTP Request node and custom code nodes handle the connection, authentication, and data format translation that no SaaS tool supports
- Call outcomes flow into your legacy ERP, accounting, or inventory system as if they came from your existing front-end applications
