An AI voice agent is most powerful when it's wired into the tools you already use — your spreadsheet, your CRM, your automation stack. This guide is the map: every way to trigger calls and capture results, with links to set each one up.

## The core idea: one API call

Everything below rests on a single endpoint. To place a call, you POST to the platform API with a phone number, an agent, and per-call variables:

```
POST https://voice-agent.edesy.in/api/initiate-call
Authorization: Bearer vp_live_your_api_key
{ "phone_number": "+919876543210", "agent_id": 123, "variables": { ... } }
```

Call **events** (ringing, answered, completed, plus captured data) flow back via [webhook subscriptions](https://edesy.in/blog/voice-ai-api-webhooks-integration-guide). That request/response pair is all any integration needs.

## Ready n8n templates

You don't have to build from scratch — these are pre-made workflows:

- **[Trigger calls from Google Sheets](https://edesy.in/blog/trigger-ai-voice-calls-from-google-sheets-n8n-2026)** — your sheet is the campaign; calls run on a schedule and write results back.
- **[Auto-call new HubSpot leads](https://edesy.in/blog/trigger-ai-voice-calls-from-hubspot-n8n-2026)** — speed-to-lead: call the moment a lead is created, log the outcome to the contact.
- **[Run a campaign from Airtable](https://edesy.in/blog/log-ai-voice-calls-to-airtable-n8n-2026)** — Airtable as a visual control panel with two-way call logging.

## Choosing your trigger

| You have… | Use | Best for |
|-----------|-----|----------|
| A list of contacts | Google Sheets template | Simple, no CRM needed |
| A CRM (HubSpot) | HubSpot template | Instant lead follow-up |
| An ops base (Airtable) | Airtable template | Visual, two-way logging |
| A custom app | The [API directly](https://edesy.in/voice-agent-api) | Full control |

## Telephony, too

Integrations aren't only about data tools — your agent also connects to a telephony provider (Twilio, Exotel, Plivo). For choosing one in India, see [multi-provider telephony in India](https://edesy.in/blog/multi-provider-telephony-india-comparison).

## What flows back

Whichever trigger you pick, each call can return structured data — captured fields, disposition, lead score — ready to write into your tool. Pair any of these with [post-call data extraction](https://edesy.in/blog/post-call-data-extraction-llm-architecture) to standardize those fields.

## Start building

Get your API key and the n8n templates on the [voice agent API](https://edesy.in/voice-agent-api) page, or set up your first automation on the [Edesy voice AI platform](https://edesy.in/voice-ai-platform).
