Xero-NetStandard

The Xero-NetStandard SDK makes it easy for developers to access Xero's APIs in their Csharp code, and build robust applications and software using small business & general ledger accounting data.

API Set	Description
`Accounting`	The Accounting API exposes accounting functions of the main Xero application (most commonly used)
Assets	The Assets API exposes fixed asset related functions of the Xero Accounting application
Files	The Files API provides access to the files, folders, and the association of files within a Xero organisation
Projects	Xero Projects allows businesses to track time and costs on projects/jobs and report on profitability
Payroll (AU)	The (AU) Payroll API exposes payroll related functions of the payroll Xero application
Payroll (UK)	The (UK) Payroll API exposes payroll related functions of the payroll Xero application
Payroll (NZ)	The (NZ) Payroll API exposes payroll related functions of the payroll Xero application
Bankfeeds	The Bankfeeds API facilitates the flow of transaction and statement data
AppStore	The AppStore API encapsulates subscription based endpoints

Xero Account Requirements

Create a free Xero user account
Login to your Xero developer dashboard and create an API application
Copy the credentials from your API app and store them using a secure ENV variable strategy
Decide the neccesary scopes for your app's functionality

Installation

This project is broken into 2 Nuget packages.

Xero.NetStandard.OAuth2 contains code to call all the XeroAPI endpoints

Xero.NetStandard.OAuth2Client code to authenticate and manage tokens

OAuth2Client README

Use Nuget to download the packages via command line:

dotnet add package Xero.NetStandard.OAuth2
dotnet add package Xero.NetStandard.OAuth2Client

Or use the Package Manager Console inside Visual Studio

Install-Package Xero.NetStandard.OAuth2
Install-Package Xero.NetStandard.OAuth2Client

You can also download the source code from https://github.com/XeroAPI/Xero-NetStandard and compile it by yourself.

To get started there are a couple main classes:

The AccountingApi class
XeroOAuth2

The AccountingApi class is not coupled to the OAuth2 class so you easily can use another OAuth2 auth flow if you prefer.

To get started you will just need two things to make calls to the Accounting Api.

xero-tenant-id
accessToken

Configuration

XeroConfiguration xconfig = new XeroConfiguration();
xconfig.ClientId = "yourClientId";
xconfig.ClientSecret = "yourClientSecret";
xconfig.CallbackUri = new Uri("https://localhost:5001"); //default for standard webapi template
xconfig.Scope = "openid profile email offline_access files accounting.transactions accounting.contacts";

var client = new XeroClient(xconfig);

Authentication

Step 1

Build the login link and send the user through the authorization_code flow (a .NET Core Mvc example):

    using Microsoft.AspNetCore.Mvc;
    using Microsoft.Extensions.Logging;
    using Xero.NetStandard.OAuth2.Client;
    using Xero.NetStandard.OAuth2.Config;
    using Xero.NetStandard.OAuth2.Token;
    using System;
    using System.Net.Http;
    using System.Threading.Tasks;
    using Xero.NetStandard.OAuth2.Models;
    using System.Collections.Generic;


    namespace XeroNetStandardApp.Controllers
    {
      public class XeroOauth2Controller : Controller
      {
        private readonly ILogger<HomeController> _logger;
        private readonly IOptions<XeroConfiguration> XeroConfig;

        public XeroOauth2Controller(IOptions<XeroConfiguration> config, ILogger<HomeController> logger)
        {
          _logger = logger;
          this.XeroConfig = config;
        }

        public IActionResult Index()
        {
          XeroConfiguration xconfig = new XeroConfiguration();
          xconfig.ClientId = "yourClientId";
          xconfig.ClientSecret = "yourClientSecret";
          xconfig.CallbackUri = new Uri("https://localhost:5001"); //default for standard webapi template
          xconfig.Scope = "openid profile email offline_access files accounting.transactions accounting.contacts";

          var client = new XeroClient(xconfig);

          return Redirect(client.BuildLoginUri());
        }
      }
    }

Step 2

The user will be redirected to login, authorise access and get redirected back to your callback

In the callback URI, Xero will return a parameter code and state (if you passed any)

code
state

You can then exchange the temp code for a XeroToken

	XeroConfiguration xconfig = new XeroConfiguration(); 
    
	xconfig.ClientId = "yourClientId";
	xconfig.ClientSecret = "yourClientSecret";
	xconfig.CallbackUri = new Uri("https://localhost:5001") //default for standard webapi template
	xconfig.Scope = "openid profile email files accounting.transactions accounting.contacts offline_access";
	
	var client = new XeroClient(xconfig);
	
	//before getting the access token please check that the state matches
	await client.RequestAccessTokenAsync(code);
    
	//from here you will need to access your Xero Tenants
	List<Tenant> tenants = await client.GetConnections();
    
	// you will now have the tenant id and access token
	foreach (Tenant tenant in tenants)
	{
		// do something with your tenant and access token
		//client.AccessToken;
		//tenant.TenantId;
	}

You can now interact with the OAuth2 token data which has been mapped from Xero's OAuth2 json response.

{
  "id_token": "xxx.yyy.zz",
  "access_token": "xxx.yyy.zzz",
  "expires_in": 1800,
  "token_type": "Bearer",
  "refresh_token": "xxxxxxxxx",
  "scope": "email profile openid accounting.transactions offline_access"
}

...to the XeroToken object model.

xeroToken.AccessToken
xeroToken.RefreshToken
xeroToken.IdToken
xeroToken.TokenType
xeroToken.ExpiresAtUtc

A NOTE on Tokens

You will still need to save the XeroToken in your datastore to keep the connection alive until you or the user disconnect. If you have a valid XeroToken in your database you can restart a XeroAPI connection by passing the token to RefreshAccessTokenAsync on an initialized client.

Auth with PKCE

First build the login link with the PKCE(Proof Key Code Exchange) flow (a .NET Core Mvc example).

PKCE is suited for mobile and desktop applications that don't have a way to keep the ClientSecret private

    using Microsoft.AspNetCore.Mvc;
    using Microsoft.Extensions.Logging;
    using Xero.NetStandard.OAuth2.Client;
    using Xero.NetStandard.OAuth2.Config;
    using Xero.NetStandard.OAuth2.Token;
    using System;
    using System.Net.Http;
    using System.Threading.Tasks;
    using Xero.NetStandard.OAuth2.Models;
    using System.Collections.Generic;


    namespace XeroNetStandardApp.Controllers
    {
      public class XeroOauth2Controller : Controller
      {
        private readonly ILogger<HomeController> _logger;
        private readonly IOptions<XeroConfiguration> XeroConfig;

        public XeroOauth2Controller(IOptions<XeroConfiguration> config, ILogger<HomeController> logger)
        {
          _logger = logger;
          this.XeroConfig = config;
        }

        public IActionResult Index()
        {
          XeroConfiguration xconfig = new XeroConfiguration();
          xconfig.ClientId = "yourClientId";
          xconfig.CallbackUri = new Uri("https://localhost:5001"); //default for standard webapi template
          xconfig.Scope = "openid profile email offline_access files accounting.transactions accounting.contacts";
	  xconfig.State = "YOUR_STATE"

          var client = new XeroClient(xconfig);

          // generate a random codeVerifier
          var validChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz-._~";          
          Random random = new Random();
          int charsLength = random.Next(43, 128);
          char[] randomChars = new char[charsLength];
          for (int i = 0; i < charsLength; i++)  
          {  
              randomChars[i] = validChars[random.Next(0, validChars.Length)];  
          }  
          string codeVerifier = new String(randomChars);

          return Redirect(client.BuildLoginUriPkce(codeVerifier));
        }
      }
    }

The user will be redirected to login, authorise access and get redirected to your callback. You can then use the RequestAccessTokenPkceAsync to exchange for a XeroToken set.

	XeroConfiguration xconfig = new XeroConfiguration(); 
	xconfig.ClientId = "yourClientId";
	xconfig.CallbackUri = new Uri("https://localhost:5001") //default for standard webapi template
	xconfig.Scope = "openid profile email files accounting.transactions accounting.contacts offline_access";
	
	var client = new XeroClient(xconfig);
  	string codeVerifier = "Aaaaaaaaaa.Bbbbbbbbbb.0000000000.1111111111";

	await client.RequestAccessTokenPkceAsync(code, codeVerifier);

Custom Connections

Custom Connections are a Xero premium option used for building M2M integrations to a single organisation. A custom connection uses OAuth2.0's client_credentials grant which eliminates the step of exchanging the temporary code for a token set.

To use this SDK with a Custom Connections var xeroTenantId = ""; must still be passed to work with a Custom Connection.

Full sample code: https://github.com/XeroAPI/Xero-NetStandard-custom-connections-starter

using System;
using Xero.NetStandard.OAuth2.Api;
using Xero.NetStandard.OAuth2.Client;
using Xero.NetStandard.OAuth2.Config;
using System.Threading.Tasks;

namespace AsyncMain
{
    class Program
    {
        static async Task Main(string[] args)
        {
            DotNetEnv.Env.Load();
            var helloWorld = await GetHelloWorldAsync();
            Console.WriteLine(helloWorld);
        }

        static async Task<string> GetHelloWorldAsync()
        {   
            XeroConfiguration XeroConfig = new XeroConfiguration
            {
                ClientId = System.Environment.GetEnvironmentVariable("CLIENT_ID"),
                ClientSecret = System.Environment.GetEnvironmentVariable("CLIENT_SECRET")
            };

            var client = new XeroClient(XeroConfig);
            var xeroToken = await client.RequestClientCredentialsTokenAsync();

            try {
                var apiInstance = new AccountingApi();
                var ifModifiedSince = DateTime.Parse("2000-02-06T12:17:43.202-08:00");
                var where = "Status==\"ACTIVE\"";
                var xeroTenantId = "";
                var result = await apiInstance.GetAccountsAsync(xeroToken.AccessToken, xeroTenantId, ifModifiedSince, where, null);
                return result.ToJson();
            }
            catch (Exception e)
            {
                Console.WriteLine("Exception when calling apiInstance.GetInvoice: " + e.Message );
                return e.ToString();
            }
        }
    }
}

Because Custom Connections are only valid for a single organisation you don't need an actual xero-tenant-id however the parameter remains and still requires an empty string.

App Store Subscriptions

If you are implementing subscriptions to participate in Xero's App Store you will need to setup App Store subscriptions endpoints. When a plan is successfully purchased, the user is redirected back to the URL specified in the setup process. The Xero App Store appends the subscription Id to this URL so you can immediately determine what plan the user has subscribed to through the subscriptions API. With your app credentials you can create a client via client_credentials grant type with the marketplace.billing scope. This unique access_token will allow you to query any functions in AppStoreApi. Client Credentials tokens to query app store endpoints will only work for apps that have completed the App Store on-boarding process.

You should use the subscription data to provision user access/permissions to your application.

App Store Subscription Webhooks

In additon to a subscription Id being passed through the URL, when a purchase or an upgrade takes place you will be notified via a webhook. You can then use the subscription Id in the webhook payload to query the AppStore endpoints and determine what plan the user purchased, upgraded, downgraded or cancelled. Refer to Xero's documenation to learn more about setting up and receiving webhooks or review this blogpost explaing webhooks using this sdk.

https://developer.xero.com/documentation/guides/webhooks/overview/

  Type = Invoice.TypeEnum.ACCREC,
  Contact = contact,
  Date = DateTime.Today,
  DueDate = DateTime.Today.AddDays(30),
  LineItems = lines
};

var invoiceList = new List<Invoice>();

Bankfeed API

Before trying the APIs, please make sure your company had been approved for Bankfeed endpoints and have the bankfeed scope enabled on your Xero OAuth 2.0 app. If you intend to become a Xero bankfeed partner please start by registering here.

Create a bankfeed connection

var feedConnection = new FeedConnection{
  AccountToken = accountToken, 
  AccountNumber = accountNumber,
  AccountType =  accountTypeEnum,
  AccountName = accountName,
  Currency = currencyCode,
  Country = countryCode
};

List<FeedConnection> list = new List<FeedConnection>();
list.Add(feedConnection);

FeedConnections items = new FeedConnections{
  Pagination = new Pagination(),
  Items = list
};

Guid bankfeedConnectionIdGuid = Guid.Parse(bankfeedConnectionId);

List<FeedConnection> list = new List<FeedConnection>();

list.Add(
  new FeedConnection {
    Id = bankfeedConnectionIdGuid
  }
);

var feedConnections = new FeedConnections{
    Items = list
};

var BankFeedsApi = new BankFeedsApi();
await BankFeedsApi.DeleteFeedConnectionsAsync(accessToken, xeroTenantId, feedConnections);

Create statements against a bankfeed connection (plase ensure your start balance, end balance and statement amounts are mathematically correct)

StartBalance startBalance = new StartBalance{
  Amount = decimal.Parse(startBalanceAmount),
  CreditDebitIndicator = startIndicatorEnum
};

StatementLine statementLine = new StatementLine{
  PostedDate = DateTime.Today,
  Description = "A bankfeed satemement description",
  Amount = 10,
  CreditDebitIndicator = startIndicatorEnum,
  TransactionId = new Guid().ToString()
};

EndBalance endBalance = new EndBalance{
  Amount = decimal.Parse(startBalanceAmount) + statementLine.Amount,
  CreditDebitIndicator = startIndicatorEnum
};

List<StatementLine> statementLines = new List<StatementLine>();
statementLines.Add(statementLine);

var statement = new Statement{
  FeedConnectionId = new Guid(feedConnectionId),
  StartDate = DateTime.Today.AddDays(-20),
  EndDate = DateTime.Today,
  StartBalance = startBalance,
  EndBalance = endBalance,
  StatementLines = statementLines,

// Convet IFormFile to byte array
byte[] byteArray; 
using (MemoryStream data = new MemoryStream())
{
  file.CopyTo(data);
  byteArray = data.ToArray();
}

// Upload file
var response = await FilesApi.UploadFileAsync(
    accessToken,
    xeroTenantId,
    null,
    byteArray,
    file.FileName,
    file.ContentType

await filesApi.DeleteFileAsync(accessToken, xeroTenantId, fileIDGuid);

Rename a File:

Guid fileIDGuid = Guid.Parse(fileID);

var filesApi = new FilesApi();
FileObject file = await filesApi.GetFileAsync(accessToken, xeroTenantId, fileIDGuid);
file.Name = newName;

var response = await filesApi.UpdateFileAsync(accessToken, xeroTenantId, fileIDGuid, file);

Get Associations

var FilesApi = new FilesApi();
var response = await FilesApi.GetFileAssociationsAsync(accessToken, xeroTenantId, new Guid(fileId));

Create an Association

var FilesApi = new FilesApi();

var fileIdGuid = new Guid(fileId);
var invoiceIdGuid = new Guid(invoiceId);
Enum.TryParse<ObjectType>(objectType, out var objectTypeEnum);

Association association = new Association{
    FileId = fileIdGuid,
    ObjectId = invoiceIdGuid,
    ObjectType = objectTypeEnum,
    ObjectGroup = ObjectGroup.Invoice
};

var response = await FilesApi.CreateFileAssociationAsync(accessToken, xeroTenantId, fileIdGuid, association);

Delete an Association

var fileIdGuid = new Guid(fileId);
var objectIdGuid = new Guid(objectId);

var FilesApi = new FilesApi();
await FilesApi.DeleteFileAssociationAsync(accessToken, xeroTenantId, fileIdGuid, objectIdGuid);

TLS 1.0 deprecation

As of June 30, 2018, Xero's API will remove support for TLS 1.0.

The easiest way to force TLS 1.2 is to set the Runtime Environment for your server (Tomcat, etc) to Java 1.8 which defaults to TLS 1.2.
