Generate API Key

Generate an API Key

API keys authenticate your voice bot or application when calling FlowCaptain's API. Each key is scoped to a specific calendar.

Creating a Key

1. Go to your FlowCaptain Dashboard
2. Navigate to the calendar you want to connect
3. Open the API Keys tab
4. Click Create API Key
5. Give it a descriptive name (e.g. "Retell Production", "VAPI Staging")
6. Copy the key immediately — it won't be shown again

Key Format

API keys follow the format sk_live_ followed by a random hex string:

sk_live_abc123def456abc123def456abc12345

Using the Key

Include the key as a Bearer token in the Authorization header of every API request:

Authorization: Bearer sk_live_your_key_here

For MCP connections (Retell MCP Nodes, VAPI), the key goes in the authentication configuration of your voice bot platform.

Key Management

• Multiple keys per calendar — Create separate keys for development, staging, and production
• Revoke anytime — Delete a key to immediately revoke access
• Rotate regularly — Create a new key, update your integration, then delete the old key

Security Tips

• Never share API keys in public repositories, chat messages, or client-side code
• Use separate keys for different environments and integrations
• Revoke keys immediately if they may have been exposed
