​
API authentication

The API uses bearer API-key authentication. 
Authorization: Bearer YOUR_API_KEY
API keys are workspace-scoped. Only organization owners and admins can generate a key from the app. IMPORTANT: Generating a new key revokes the previous key for that workspace. Example: 
curl "https://api.talktohumans.app/v1/organization" \
  -H "Authorization: Bearer $TTH_API_KEY"

​
MCP authentication

The MCP uses OAuth bearer authentication, not TalkToHumans API keys. MCP endpoint: 
https://api.talktohumans.app/mcp
