Introduction: Getting Started with Xero’s Accounting API

Welcome, Xero developers! Have you ever wondered how to integrate Xero’s accounting features into your own applications? This guide will give you a step-by-step introduction to getting started with the Xero Accounting API. From authentication to posting invoices, we will cover it all. 

Setting up Your Environment

SDK and OAuth 2.0

Before making any API calls, you will need to set up your SDK (Software Development Kit). Xero offers various SDKs suitable for all types of development environments. OAuth 2.0 is used for authentication; make sure to obtain your client ID and client secret.

Xero Organisation and Endpoint

You will need a Xero organisation to connect to the API. Endpoints are the functions available in the API, e.g., ‘GetInvoices’ or ‘PostPayments’.

Integration Best Practices

  • Rate Limit: Be mindful of the API’s rate limit to avoid being temporarily blocked.
  • Validation Errors: Check the API documentation for error codes to simplify debugging.

Step 1: Sign Up for a Free Xero Account

To get started, sign up for a free Xero account. This will give you access to the Xero Developer Centre and a demo company to test your API calls.

Step 2: Authorise Your App

Utilise OAuth 2.0 to authorise your app to get access to the Xero organisation. You will be redirected back to your specified redirect URI.

Step 3: Make Your First API Call

Now that you have authorised your app, you can make your first API call to post invoices or get account code details.

Step 4: Tax Rate and Line Item Details

Each invoice requires a tax rate and line item details. These can be posted via the API using the respective endpoints.

Step 5: Pagination and Callback

When dealing with multiple invoices, pagination can be useful. For real-time updates, use callbacks.

Integration: Partner with Xero for More Advanced Features

If you find that the Xero API meets your needs and you want to explore more advanced features, consider becoming a Xero App partner. This opens up custom connections and additional support from the Xero developer team.
