Generate API Key

Generate an API Key

API keys authenticate your voice bot or application when calling FlowCaptain's API. Each key is account-level and works for every calendar in your account — so each API request must specify which calendar it targets via calendarId.

Creating a Key

1. Open the workspace Settings in FlowCaptain
2. Scroll to the API Keys section
3. Click Create API Key
4. Give it a descriptive name (e.g. "Retell Production", "VAPI Staging")
5. Copy the key immediately — it won't be shown again

After creation, the overview only shows the key's prefix (e.g. sk_live_xxxx...), plus status, last used, and creation date.

Key Format

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

sk_live_<your_random_hex_string>

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. In your calendar's Integration Guide, the header is already pre-filled with your active key prefix.

Key Management

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