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. 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 — your sheet is the campaign; calls run on a schedule and write results back.
- Auto-call new HubSpot leads — speed-to-lead: call the moment a lead is created, log the outcome to the contact.
- Run a campaign from Airtable — 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 | 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.
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 to standardize those fields.
