If you are a developer or business owner who wants to connect applications with Xero, the Xero API is the best tool for you. Xero is a cloud-based accounting software that helps businesses manage invoices, expenses, payroll, and financial reports.
With the Xero API, you can build apps, automate accounting tasks, and integrate Xero with other platforms. In this guide, we will explain everything in simple words so you can understand how Xero API works.
What is Xero API?
The Xero API (Application Programming Interface) is a system that allows developers to connect their apps to Xero. It helps businesses:
- Automate accounting processes
- Sync financial data with other software
- Generate reports in real-time
- Manage invoices, payments, and payroll
To use the Xero API, you need to create an app, authenticate it, and send API requests. Let’s go step by step.
Getting Started: Xero API Documentation
Before working with the Xero API, you should check the Xero API documentation. This is the official guide from Xero that explains how to use the API. It includes details about authentication, endpoints, rate limits, and more.
How to Integrate with Xero API?
To connect an app with Xero, follow these steps:
- Register as a Xero API Developer Sign up for a Xero Developer Account at developer.xero.com. Create a new app in the Xero Developer Dashboard.
- Xero API Authentication
To keep data safe, Xero requires OAuth 2.0 authentication. This means you must get permission before accessing a user’s data.
Steps to authenticate:
Get a client ID and client secret from Xero.
Use OAuth 2.0 to request an access token.
Use the access token to make API requests.
Xero API Endpoints: What Can You Do?
API endpoints are like doors that let you access different features in Xero. Here are some important ones:
Xero API Endpoint Function
/Invoices Create, update, or retrieve invoices
/Contacts Manage customer and supplier details
/Payments Record payments and refunds
/BankTransactions Handle bank feeds and transactions
/Payroll Manage employee payroll
When you send a request to these endpoints, Xero will send back a response with the requested data.
Xero API Requests and Responses
Every time you send a request, you will get a response. Requests are usually sent in JSON format, and responses are also returned in JSON.
Example: Get All Contacts
Request (GET method)
json
CopyEdit
GET https://api.xero.com/api.xro/2.0/Contacts
Response
json
CopyEdit
{ "Contacts": [ { "ContactID": "12345", "Name": "John's Store", "EmailAddress": "john@example.com" } ] }
This response shows a contact named John’s Store with an email address.
Xero API Rate Limits: How Many Requests Can You Make?
Xero has API rate limits to prevent excessive requests. If you send too many requests in a short time, Xero will block your access temporarily.
Xero API Rate Limits
Minute Limit: 60 API calls per minute
Daily Limit: 5,000 API calls per day
Concurrent Limit: 10 active connections
If you reach the limit, wait for a while before sending new requests.
Xero API Best Practices
To avoid errors and ensure smooth integration, follow these best practices:
✔ Use OAuth 2.0 Authentication – Securely connect to Xero.
✔ Respect API Rate Limits – Avoid being blocked.
✔ Handle Errors Properly – Use try-catch methods in code.
✔ Keep Your App Updated – Xero updates its API frequently.
Xero API Webhooks: Get Real-Time Updates
Instead of manually checking data, you can use Xero API Webhooks. Webhooks send automatic notifications when something changes in Xero.
Example: Invoice Payment Webhook
If a customer pays an invoice, Xero can notify your app instantly, so you don’t have to check manually.
Xero API SDKs: Make Development Easier
SDKs (Software Development Kits) help developers integrate faster. Xero provides SDKs for different programming languages:
- Xero API SDK for Python
- Xero API SDK for JavaScript
- Xero API SDK for PHP
- Xero API SDK for .NET
These SDKs contain pre-written code to help you connect to Xero quickly.
