Build on the iovox platform.
Integrate voice, SMS, email, live chat and call data into your apps and platforms. Five APIs. One unified data model. Telco-grade infrastructure active in 65+ countries.
What are the iovox APIs?
The iovox APIs build call tracking into your own platform. You can buy and configure tracking numbers in 65+ countries, retrieve recordings and transcripts over REST, receive webhook events and use native Salesforce, HubSpot and Zoho connectors.
Five APIs. Every communications channel.
Each API is independently usable or combined into a unified communications and analytics layer for your platform. All ship with full REST documentation, a sandbox environment and webhook event streams.
Purchase and configure tracking numbers in 65+ countries, build call flows, enable WebConnect, retrieve recordings and transcriptions, all via REST.
- Automated number provisioning per listing, ad, or campaign
- Call Rules: routing, whispers, IVR, and fallback logic
- Recordings, transcriptions, and conversational AI data
Bidirectional SMS with full analytics. Proxy messaging, SMS-to-voice conversion, and trackable message threads built for marketplaces.
- Send and receive SMS via proxy, both parties stay anonymous
- SMS-to-voice: read messages aloud as a phone call
- Response time tracking, thread analytics, webhook events
Track email as a first-class communications event. Open rates, link clicks and engagement metrics, via on-the-fly proxy addresses.
- Proxy email addresses provisioned on demand
- Delivery status, open and click events via webhook

Aggregate call data from any source (iovox numbers, Cisco UCM, BroadWorks, Asterisk, Avaya, or mobile) for speech analytics and quality control.
- Ingest calls from third-party PBX and telephony systems
- Sentiment analysis, scoring and compliance checks
- Push enriched call data to your BI or CRM stack
The building blocks developers use most.
WebConnect
Let website visitors initiate a trackable phone call from their browser using WebRTC, no virtual number required, fully customisable behaviour.
SMS Tracking
Track message exchanges between buyers and sellers while keeping both parties anonymous. Response times, thread length, conversion outcomes.
Call Rules API
Build simple or sophisticated call routing logic programmatically: IVR menus, time-based routing, team fallback, whisper injection and more.
JavaScript API
Dynamic Number Insertion for web. Swap phone numbers per visitor session to attribute every web call to its exact source, campaign, and keyword.
iovox Insights API
Retrieve call data enriched with conversational AI analytics: transcriptions, keyword spotting, sentiment scores and intent tags.
Webhooks
Real-time event streams for every call lifecycle event (start, answer, end, transcription complete, score ready), delivered to any endpoint.

What can I build with the iovox APIs?
Call, SMS, email and live chat tracking inside your own platform. There are five APIs (Voice, SMS, Email, Live Chat and Call Data), each usable on its own or combined.
Does iovox offer webhooks?
Yes. All five APIs send webhook events, such as call events, SMS thread activity, email delivery, opens and clicks, and chat sessions starting, receiving messages and closing.
Is there a sandbox for testing the iovox APIs?
Yes. Every API comes with full REST documentation, an OpenAPI spec, a sandbox environment and SDKs.
Can I provision tracking numbers through the API?
Yes. The Voice API buys and configures local, national and toll-free numbers in 65+ countries, with automated provisioning per listing, ad or campaign.
