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
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/fathom/external/v1/meetings')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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 $MATON_API_KEY

Environment Variable: Set your API key as

MATON_API_KEY

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

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

Connection Management

Manage your Fathom OAuth connections at

https://ctrl.maton.ai

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=fathom&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Create Connection

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'fathom'}).encode()
req = urllib.request.Request('https://ctrl.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Get Connection

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Specifying Connection

If you have multiple Fathom connections, specify which one to use with the

Maton-Connection

header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/fathom/external/v1/meetings')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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

Code Examples

JavaScript

const response = await fetch(
  'https://gateway.maton.ai/fathom/external/v1/meetings?created_after=2025-01-01T00:00:00Z',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();

Python

import os
import requests
response = requests.get(
'https://gateway.maton.ai/fathom/external/v1/meetings&#x27;,
headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
params={'created_after': '2025-01-01T00:00:00Z'}
)
data = response.json()

Notes

Recording IDs are integers
Timestamps are in ISO 8601 format
Transcripts and summaries are in English
Webhook secrets are used to verify webhook signatures
CRM matches only return data from your or your team's linked CRM
IMPORTANT: When using curl commands, use
```
curl -g
```
when URLs contain brackets (
```
fields[]
```
,
```
sort[]
```
,
```
records[]
```
) to disable glob parsing
IMPORTANT: When piping curl output to
```
jq
```
or other commands, environment variables like
```
$MATON_API_KEY
```
may not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.

Error Handling

Status	Meaning
400	Bad request or missing Fathom connection
401	Invalid or missing Maton API key
404	Resource not found
429	Rate limited
4xx/5xx	Passthrough error from Fathom API

Troubleshooting: API Key Issues

Check that the
```
MATON_API_KEY
```
environment variable is set:

echo $MATON_API_KEY

Verify the API key is valid by listing connections:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Troubleshooting: Invalid App Name

Ensure your URL path starts with
```
fathom
```
. For example:

Correct:

https://gateway.maton.ai/fathom/external/v1/meetings

Incorrect:

https://gateway.maton.ai/external/v1/meetings
