Voice AI API
Build directly on VoiTech's voice agent platform.
For businesses that want to go beyond out-of-the-box configuration, VoiTech's voice AI API gives developers direct, programmatic access to the platform — with websocket support for real-time interaction and SDKs for Python, Node.js and Go, so custom voice experiences can be built on infrastructure VoiTech already runs and maintains.
Key features
Websocket-based real-time access
Build real-time voice interactions rather than being limited to request/response style integrations.
Python, Node.js and Go SDKs
Official SDKs cover the languages most commonly used for backend and automation work, with clear documentation.
Programmatic call control
Trigger calls, control call flow, and pull call data programmatically rather than only through the dashboard.
Event-driven integrations
Hook into call events to trigger your own systems and workflows the moment something happens on a call.
Benefits
- Build custom voice experiences without standing up your own telephony and AI infrastructure
- Integrate voice AI directly into your own product or internal tools
- Real-time access via websockets rather than polling
- Official SDKs reduce integration time for common backend languages
How it works
Get API access
Request API credentials through your VoiTech account.
Install an SDK or call the API directly
Use the Python, Node.js or Go SDK, or integrate directly via REST/websocket.
Build your integration
Trigger calls, handle real-time events, and pull call data into your own systems.
Go live
Move from testing to production once your integration is ready.
Integrations
Built for UK businesses
API infrastructure runs within VoiTech's UK/EU regions, so data residency requirements are maintained even for fully custom integrations.
