Fathom

Fathom

Access the Fathom API with managed OAuth authentication. Retrieve meeting recordings, transcripts, summaries, action items, and manage webhooks for notifications.

Quick Start

# List recent meetings
curl -s -X GET 'https://gateway.maton.ai/fathom/external/v1/meetings' \
  -H 'Authorization: Bearer YOUR_API_KEY'

Base URL

https://gateway.maton.ai/fathom/{native-api-path}

Replace {native-api-path} with the actual Fathom API endpoint path. The gateway proxies requests to api.fathom.ai and automatically injects your OAuth token.

Authentication

All requests require the Maton API key in the Authorization header:

Authorization: Bearer YOUR_API_KEY

Environment Variable: Set your API key as MATON_API_KEY:

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

1. Sign in or create an account at maton.ai
2. Go to maton.ai/settings
3. Copy your API key

Connection Management

Manage your Fathom OAuth connections at https://ctrl.maton.ai.

List Connections

curl -s -X GET 'https://ctrl.maton.ai/connections?app=fathom&status=ACTIVE' \
  -H 'Authorization: Bearer YOUR_API_KEY'

Create Connection

curl -s -X POST 'https://ctrl.maton.ai/connections' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -d '{"app": "fathom"}'

Get Connection

curl -s -X GET 'https://ctrl.maton.ai/connections/{connection_id}' \
  -H 'Authorization: Bearer YOUR_API_KEY'

Response:

{
  "connection": {
    "connection_id": "21fd90f9-5935-43cd-b6c8-bde9d915ca80",
    "status": "ACTIVE",
    "creation_time": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "fathom",
    "metadata": {}
  }
}

Open the returned url in a browser to complete OAuth authorization.

Delete Connection

curl -s -X DELETE 'https://ctrl.maton.ai/connections/{connection_id}' \
  -H 'Authorization: Bearer YOUR_API_KEY'

Specifying Connection

If you have multiple Fathom connections, specify which one to use with the Maton-Connection header:

curl -s -X GET 'https://gateway.maton.ai/fathom/external/v1/meetings' \
  -H 'Authorization: Bearer YOUR_API_KEY' \
  -H 'Maton-Connection: 21fd90f9-5935-43cd-b6c8-bde9d915ca80'

If omitted, the gateway uses the default (oldest) active connection.
