Setup Steps
- Step 1: Sign in to your ElevenLabs dashboard and copy an API key from Profile → API Keys.
- Step 2: In Falcon Builder, go to Dashboard → Credentials → Add Credential and pick ElevenLabs.
- Step 3: Paste the API key. Optionally pre-fill a default agent ID and default phone number ID — these become defaults on new ElevenLabs nodes.
- Step 4: A Webhook Signing Secret is auto-generated. Copy it into your ElevenLabs post-call webhook settings so we can verify webhook origin when call-completion events arrive.
- Step 5: Click Test Credential. We hit
GET /v1/voicesand confirm the voice count.
Twilio for outbound calls
To place outbound calls from an ElevenLabs agent, configure your Twilio credentials inside the ElevenLabs dashboard (Conversational AI → Phone Numbers → Import). Falcon Builder triggers calls through ElevenLabs; we do not store Twilio credentials for the purpose of forwarding them.
