Xero

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

Quick Start

# 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/api.xro/2.0/{endpoint}

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:

export MATON_API_KEY="YOUR_API_KEY"

Sign in at maton.ai
Go to maton.ai/settings
Copy your API key
