AIOnCalls Developer API — REST API and Webhooks for triggering AI voice agent calls, managing agents, syncing CRM data, and receiving real-time call events.

Developer API

Build Custom Automation on the AIOnCalls REST API

Trigger outbound AI voice agent calls, receive real-time call event webhooks, sync CRM data, and manage agents programmatically — with scoped API keys issued from a self-serve developer portal. For no-code CRM and workflow-tool connections, see Integrations; for guided setup walkthroughs, see the documentation.

API Capabilities

What You Can Build With the AI Voice Agent API

A REST API and outbound event webhooks for developers who want to trigger calls, manage agents, and sync data from their own applications — not just connect no-code tools.

Call Trigger

Start an outbound AI voice agent call from your own application using a scoped API key — the same call-trigger capability that powers every no-code automation on the Integrations page, available directly to your code.

Call Event Webhooks

Receive real-time events as a call progresses, straight to your own endpoint — no polling required.

call.initiated · answered · completed · failed · no-answer · busy
Agents & Usage

Manage AI voice agents, clone agent templates, and pull usage data programmatically through the same REST API.

CRM Sync

Push call outcomes and lead data to your CRM the moment a conversation ends — the same sync that powers native Salesforce, HubSpot, and Zoho integration, exposed as an API for custom CRMs.

Scoped Authentication

Secure, scoped API keys — issue read-only or full call-trigger keys, and manage them from the self-serve developer portal.

Developer Portal

Self-serve API key management, webhook configuration, and live testing tools — no support ticket required to get started.

Public REST API and webhook access is included on the Business plan and above, and available as an add-on on Growth. See plans & pricing for details.
Quickstart

Three Steps to Your First API Call

Get a scoped API key

Sign in to the developer portal and generate a scoped API key — read-only for usage data, or full access to trigger calls and manage agents.

Call the API or set a webhook URL

Trigger an outbound call from your own backend, or register a webhook endpoint to receive call events as they happen — both authenticated with the same scoped key.

React to real-time events

Your endpoint receives call.initiated, answered, completed, and outcome events as they fire, so your own systems — not just AIOnCalls' — stay in sync.

Example — illustrative request shape Illustrative
# Authenticate with a scoped API key from your developer portal
curl -X POST https://api.aioncalls.com/v1/calls \
  -H "Authorization: Bearer YOUR_SCOPED_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "agent_id": "your_agent_id", "to": "+1..." }'

# Your webhook endpoint then receives events as the call progresses
call.initiated → call.answered → call.completed

Exact field names, endpoints, and full request/response schemas are provided in your developer portal once API access is enabled on your plan.

Outbound Event Webhooks

Every Call, Every Stage, In Real Time

Outbound event webhooks fire the moment a call changes state, so your CRM, dashboard, or custom application always reflects what's actually happening on the line.
