HubSpot
Access the HubSpot CRM API with managed OAuth authentication. Create and manage contacts, companies, deals, and their associations.
Quick Start
# List contacts
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/hubspot/crm/v3/objects/contacts?limit=10&properties=email,firstname,lastname')
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/hubspot/{native-api-path}
Replace {native-api-path} with the actual HubSpot API endpoint path. The gateway proxies requests to api.hubapi.com 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 HubSpot 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=hubspot&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': 'hubspot'}).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:
json
{
"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": "hubspot",
"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 HubSpot 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/hubspot/crm/v3/objects/contacts')
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.

Notes
- Batch operations support up to 100 records per request
- Archive/Delete is a soft delete - records can be restored within 90 days
- Delete endpoints return HTTP 204 (No Content) on success
- The
industryproperty on companies requires specific enum values - IMPORTANT: When using curl commands, use
curl -gwhen URLs contain brackets (fields[],sort[],records[]) to disable glob parsing - IMPORTANT: When piping curl output to
jqor other commands, environment variables like$MATON_API_KEYmay not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.
Error Handling
| Status | Meaning |
|---|---|
| 400 | Missing HubSpot connection |
| 401 | Invalid or missing Maton API key |
| 429 | Rate limited (10 req/sec per account) |
| 4xx/5xx | Passthrough error from HubSpot API |
Troubleshooting: API Key Issues
- Check that the
MATON_API_KEYenvironment 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
hubspot. For example:
- Correct:
https://gateway.maton.ai/hubspot/crm/v3/objects/contacts - Incorrect:
https://gateway.maton.ai/crm/v3/objects/contacts
