VAPI Integration Guide
Connect your AI agent to VAPI for AI-powered voice calls, phone tree automation, call transcription, and real-time voice agent capabilities.
What your agent can do
Voice AI capabilities through the VAPI platform.
AI voice calls
Make and receive phone calls powered by AI. Your agent can have natural voice conversations with customers, handle inbound calls, and conduct outbound outreach.
Phone tree automation
Navigate interactive voice response (IVR) systems automatically. Your agent can call businesses, press through menus, and reach the right department.
Call transcription
Get real-time and post-call transcriptions of every conversation. Your agent can log call summaries, extract action items, and update your CRM.
Real-time voice agent
Run a live voice agent that responds in real time with sub-second latency. Handle customer support, appointment booking, and qualification calls.
Prerequisites
What you need before connecting VAPI to your agent.
- A VAPI account (sign up at vapi.ai)
- An API key from the VAPI dashboard
- A phone number configured in VAPI (for call features)
- A ClawTrust agent on any plan (Starter, Pro, or Enterprise)
Step-by-step setup
Connect VAPI to your agent in about 5 minutes.
Create a VAPI account
Go to vapi.ai and sign up for an account. VAPI offers a free tier for testing. Once registered, you will be taken to the dashboard.
Generate an API key
In the VAPI dashboard, go to Settings > API Keys and create a new key. Label it "ClawTrust" for easy identification. Copy the key immediately.
Configure a phone number (optional)
If you want your agent to make or receive phone calls, go to Phone Numbers in the VAPI dashboard and either buy a new number or connect an existing Twilio number.
Add the credential in ClawTrust
In your agent's dashboard, go to Credentials > Add Credential. Select "API Key (Bearer)" as the type. Paste your VAPI API key as the value. Set allowed domains to *.vapi.ai.
Test the connection
Click "Test" on the credential card. ClawTrust will verify API access against the VAPI endpoint. You can then ask your agent to initiate a test call to confirm end-to-end functionality.
Credential details
Reference for the credential configuration fields.
Security note
Your VAPI API key is encrypted with AES-256-GCM before storage. The credential proxy restricts all outbound requests to *.vapi.ai domains only. You can regenerate the API key from the VAPI dashboard at any time to revoke access. Call recordings and transcriptions are stored on VAPI's infrastructure, not on the ClawTrust control plane.
Example actions
