VoiceInfra works in both directions with automation platforms. When a call completes, VoiceInfra can fire a webhook to Zapier, Make.com, n8n, or Pipedream — triggering any downstream action across thousands of connected apps. In the other direction, your automation platform can call the VoiceInfra Dynamic Outbound Call API to initiate an AI call the moment a trigger fires, such as a new lead appearing in your CRM or a form submission landing in your database.

​
Two Integration Patterns

​
1. VoiceInfra → Automation Platform

When a call completes, VoiceInfra sends a POST request to your configured webhook URL. Your automation platform receives the payload (call ID, transcript, outcome, recording URL, and more), and your Zap, scenario, or workflow fires immediately. Use this pattern to:
  • Update a CRM record after every call
  • Send a Slack or Teams message to your sales team when a hot lead calls
  • Add a row to Google Sheets with call outcome data
  • Create a Zendesk ticket when a support call ends
  • Send a follow-up email via Gmail or Outlook

​
2. Automation Platform → VoiceInfra

Your automation platform sends a POST request to the VoiceInfra Dynamic Outbound Call API. VoiceInfra immediately places an outbound call with your configured AI agent. Use this pattern to:
  • Call a new lead the instant they submit a web form
  • Trigger appointment reminder calls from your calendar system
  • Follow up on unpaid invoices from your billing platform
  • Initiate survey calls after a support ticket closes

​
Setting Up Zapier

1

Copy your VoiceInfra webhook URL

In VoiceInfra, go to Settings → Webhooks → Add Webhook. Enter a name, generate your endpoint URL, and copy it. See the Webhooks guide for full configuration steps.
2

Create a new Zap with "Webhooks by Zapier" as the trigger

In Zapier, click Create Zap. Search for and select Webhooks by Zapier as your trigger app, then choose Catch Hook as the trigger event.
3

Paste the VoiceInfra webhook URL into Zapier

Zapier provides a unique webhook URL for this Zap. Paste that URL into the VoiceInfra webhook configuration as your endpoint. Save both.
4

Test with a live call

Make a call to your VoiceInfra number. When the call completes, VoiceInfra sends a sample payload to Zapier. Click Test Trigger in Zapier to confirm it received the data.
5

Add your desired actions

In Zapier, add one or more action steps using the call data fields from the payload — update a CRM record, post a Slack message, create a calendar event, send an email, or anything else your Zapier plan supports.
6

Turn on the Zap

Toggle the Zap to On. Every subsequent call completion now fires your workflow automatically.

​
Setting Up Outbound Call Triggers

To trigger an outbound AI call from your automation platform, configure a step that sends a POST request to the VoiceInfra Outbound Call API when an event occurs — such as a new lead being created, a form being submitted, or a CRM lead score reaching a threshold. 
{
  "agent_id": "agent_abc123",
  "to_number": "+14155550100",
  "from_number": "+18005551234",
  "custom_data": {
    "contact_name": "Sarah Johnson",
    "lead_source": "Website Form",
    "inquiry_topic": "Enterprise pricing"
  }
}
In Zapier, use the Webhooks by Zapier action with POST as the method. In Make.com, use the HTTP → Make a request module. In n8n, use the HTTP Request node.
The custom_data object passes context to the AI agent. Your agent prompt can reference these fields to personalize the opening of the call.

​
Real-Time In-Call Actions vs. Post-Call Webhooks

Webhooks and automation platforms work on completed calls. If you need your agent to take an action during a live call — such as booking an appointment in Google Calendar mid-conversation, or looking up a customer record while the caller is on the line — use MCP Servers instead.

​
Post-Call Email Automation

VoiceInfra includes built-in SMTP/TLS email support for automated post-call summaries. Instead of routing through Zapier to send an email, configure your SMTP server directly in Settings → Email (SMTP). After each call, VoiceInfra sends a formatted email with the call summary, recording link, transcript, and AI-extracted next steps — automatically, without a Zap task being consumed. Compatible SMTP providers: Gmail, Outlook, SendGrid, AWS SES, Mailgun, and any custom SMTP server.

Frequently Asked Questions

Yes. If you configure a webhook trigger inside a conversation flow (not just post-call), Zapier can process data and return a response to the VoiceInfra agent in real time. The agent uses the returned data to inform its next response.
Yes. Each call completion that fires your Zap counts as one task against your Zapier plan. Monitor your usage in the Zapier dashboard. If task volume is high, consider native webhooks with server-side processing instead.
Yes. In Make.com, add an HTTP → Make a request module and configure it to POST to the VoiceInfra Dynamic Outbound Call API. Set this as a step in any scenario that should initiate a call.
Webhooks fire after a call ends and deliver call data to your systems. MCP servers are called by the AI agent during a live call to fetch data or trigger actions in real time. Use webhooks for post-call automation and MCP for mid-call interactions.
VoiceInfra is a cloud platform. n8n can be self-hosted on your own infrastructure and connect to VoiceInfra via webhooks and the REST API — your n8n instance just needs to be able to receive POST requests from VoiceInfra’s servers.
