Xero

Access the Xero API with managed OAuth authentication. Manage contacts, invoices, payments, bank transactions, and run financial reports.

Quick Start

# List contacts
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/xero/api.xro/2.0/Contacts')
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/xero/{native-api-path}

Replace

{native-api-path}

with the actual Xero API endpoint path. The gateway proxies requests to

api.xero.com

and automatically injects your OAuth token and Xero-Tenant-Id header.

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 Xero 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=xero&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': 'xero'}).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": "xero",
    "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 Xero 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/xero/api.xro/2.0/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.

    }
  }
);

Python

import os
import requests
response = requests.get(
'https://gateway.maton.ai/xero/api.xro/2.0/Contacts&#x27;,
headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)

Notes

```
Xero-Tenant-Id
```
header is automatically injected
Dates are in
```
YYYY-MM-DD
```
format
Multiple records can be created in a single request using arrays
Use
```
where
```
query parameter for filtering
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	Missing Xero connection
401	Invalid or missing Maton API key
429	Rate limited (10 req/sec per account)
4xx/5xx	Passthrough error from Xero 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
```
xero
```
. For example:

Correct:

https://gateway.maton.ai/xero/api.xro/2.0/Contacts

Incorrect:

https://gateway.maton.ai/api.xro/2.0/Contacts
