Xero

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

Quick Start

```bash

List contacts

curl -s -X GET 'https://gateway.maton.ai/xero/api.xro/2.0/Contacts' \

-H 'Authorization: Bearer YOUR_API_KEY'

```

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 YOUR_API_KEY

```

**Environment Variable:** Set your API key as `MATON_API_KEY`:

```bash

export MATON_API_KEY="YOUR_API_KEY"

```

Getting Your API Key

1. Sign in or create an account at [maton.ai](https://maton.ai)

2. Go to [maton.ai/settings](https://maton.ai/settings)

3. Copy your API key

Connection Management

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

List Connections

```bash

curl -s -X GET 'https://ctrl.maton.ai/connections?app=xero&status=ACTIVE' \

-H 'Authorization: Bearer YOUR_API_KEY'

```

Create Connection

```bash

curl -s -X POST 'https://ctrl.maton.ai/connections' \

-H 'Content-Type: application/json' \

-H 'Authorization: Bearer YOUR_API_KEY' \

-d '{"app": "xero"}'

```

Get Connection

```bash

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

-H 'Authorization: Bearer YOUR_API_KEY'

```

**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": "xero",

"metadata": {}

}

}

```

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

Delete Connection

```bash

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

-H 'Authorization: Bearer YOUR_API_KEY'

```

Specifying Connection

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

```bash

curl -s -X GET 'https://gateway.maton.ai/xero/api.xro/2.0/Contacts' \

-H 'Authorization: Bearer YOUR_API_KEY' \

-H 'Maton-Connection: 21fd90f9-5935-43cd-b6c8-bde9d915ca80'

```

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