Installation

To install this gem to your current gemset.

gem install 'xero-ruby'

Or add to your gemfile and run bundle install.

gem 'xero-ruby'

Getting Started

• Create a free Xero user account
• Login to your Xero developer /myapps dashboard & create an API application and note your API app's credentials.

Creating a Client

• Get the credential values from an API application at https://developer.xero.com/myapps/.
• Include neccesary scopes as comma seperated list
  • example => "openid profile email accounting.transactions accounting.settings"

require 'xero-ruby'

creds = {
  client_id: ENV['CLIENT_ID'],
  client_secret: ENV['CLIENT_SECRET'],
  redirect_uri: ENV['REDIRECT_URI'],
  scopes: ENV['SCOPES']
}
xero_client ||= XeroRuby::ApiClient.new(credentials: creds)

User Authorization & Callback

All API requests require a valid access token to be set on the client.

To generate a valid token_set send a user to the authorization_url:

@authorization_url = xero_client.authorization_url

redirect_to @authorization_url

Xero will then redirect back to the URI defined in your ENV['REDIRECT_URI'] variable. This must match exactly with the variable in your /myapps dashboard.

In your callback route catch, calling get_token_set_from_callback will exchange the temp code in your params, with a valid token_set that you can use to make API calls.

# => http://localhost:3000/oauth/callback

token_set = xero_client.get_token_set_from_callback(params)

# save token_set JSON in a datastore in relation to the user authentication

Making API calls once you have a token_set

For use outside of the initial auth flow, setup the client by passing the whole token_set to refresh_token_set or set_token_set.

xero_client.refresh_token_set(user.token_set)

xero_client.set_token_set(user.token_set)

A token_set contains data about your API connection most importantly :

• access_token
• refresh_token
• expiry

An access_token is valid 30 minutes and a refresh_token is valid for 60 days

Example Token set:

You can decode the id_token & access_token for additional metadata by using a decoding library:

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

Token & SDK Helpers

Refresh/connection helpers

@token_set = xero_client.refresh_token_set(user.token_set)

# Xero's tokens can potentially facilitate (n) org connections in a single token. It is important to store the `tenantId` of the Organisation your user wants to read/write data.

# The `updatedDateUtc` will show you the most recently authorized Tenant (AKA Organisation)
connections = xero_client.connections
[{
  "id" => "xxx-yyy-zzz",
  "tenantId" => "xxx-yyy-zzz",
  "tenantType" => "ORGANISATION",
  "tenantName" => "Demo Company (US)",
  "createdDateUtc" => "2019-11-01T20:08:03.0766400",
  "updatedDateUtc" => "2020-04-15T22:37:10.4943410"
}]

# disconnect an org from a user's connections. Pass the connection ['id'] not ['tenantId']. Useful if you want to enforce only a single org connection per token.
remaining_connections = xero_client.disconnect(connections[0]['id'])

# set a refreshed token_set
token_set = xero_client.set_token_set(user.token_set)

# access token_set once it is set on the client
token_set = xero_client.token_set

Example token expiry helper

require 'jwt'

def token_expired?
  token_expiry = Time.at(decoded_access_token['exp'])
  token_expiry > Time.now
end

def decoded_access_token
  JWT.decode(token_set['access_token'], nil, false)[0]
end

API Usage

  require 'xero-ruby'

  xero_client.refresh_token_set(user.token_set)

  tenant_id = user.active_tenant_id
  # example of how to store the `tenantId` of the specific tenant (aka organisation)

  # https://github.com/XeroAPI/xero-ruby/blob/master/accounting/lib/xero-ruby/api/accounting_api.rb
  
  # Get Accounts
  accounts = xero_client.accounting_api.get_accounts(tenant_id).accounts

  # Create Invoice
  invoices = { invoices: [{ type: XeroRuby::Accounting::Invoice::ACCREC, contact: { contact_id: contacts[0].contact_id }, line_items: [{ description: "Big Agency", quantity: BigDecimal("2.0"), unit_amount: BigDecimal("50.99"), account_code: "600", tax_type: XeroRuby::Accounting::TaxType::NONE }], date: "2019-03-11", due_date: "2018-12-10", reference: "Website Design", status: XeroRuby::Accounting::Invoice::DRAFT }]}
  invoice = xero_client.accounting_api.create_invoices(tenant_id, invoices).invoices.first

  # Create History
  payment = xero_client.accounting_api.get_payments(tenant_id).payments.first
  history_records = { history_records: [{ details: "This payment now has some History!" }]}
  payment_history = xero_client.accounting_api.create_payment_history(tenant_id, payment.payment_id, history_records)

  # Create Attachment
  account = xero_client.accounting_api.get_accounts(tenant_id).accounts.first
  file_name = "an-account-filename.png"
  opts = {
    include_online: true
  }
  file = File.read(Rails.root.join('app/assets/images/xero-api.png'))
  attachment = xero_client.accounting_api.create_account_attachment_by_file_name(tenant_id, @account.account_id, file_name, file, opts)

  # https://github.com/XeroAPI/xero-ruby/blob/master/accounting/lib/xero-ruby/api/asset_api.rb
  
  # Create Asset
  asset = {
    "assetName": "AssetName: #{rand(10000)}",
    "assetNumber": "Asset: #{rand(10000)}",
    "assetStatus": "DRAFT"
  }
  asset = xero_client.asset_api.create_asset(tenant_id, asset)

  # https://github.com/XeroAPI/xero-ruby/blob/master/docs/projects/ProjectApi.md

  # Get Projects
  projects = xero_client.project_api.get_projects(tenant_id).items

BigDecimal

All monetary and fields and a couple quantity fields utilize BigDecimal

  puts invoice.unit_amount
  => 0.2099e2
  
  puts invoice.unit_amount.class 
  => BigDecimal

  puts invoice.unit_amount.to_s("F")
  => "20.99"

  # Rails method-number_to_currency
  number_to_currency(invoice.unit_amount, :unit => "$")

Querying & Filtering

Examples for the opts (options) parameters most endpoints support.

# Invoices
opts = { 
  statuses: [XeroRuby::Accounting::Invoice::PAID],
  where: { amount_due: '=0' },
  if_modified_since: (DateTime.now - 1.hour).to_s
}
xero_client.accounting_api.get_invoices(tenant_id, opts).invoices

# Contacts 
opts = {
  if_modified_since: (DateTime.now - 1.weeks).to_s,
  order: 'UpdatedDateUtc DESC',
  where: {
    is_customer: '==true',
    is_supplier: '==true',
  }
}
xero_client.accounting_api.get_contacts(tenant_id, opts).contacts

# Bank Transactions
opts = {
  if_modified_since: (DateTime.now - 1.year).to_s,
  where: { type: %{=="#{XeroRuby::Accounting::BankTransaction::SPEND}"}},
  order: 'UpdatedDateUtc DESC',
  page: 2,
  unitdp: 4 # (Unit Decimal Places)
}
xero_client.accounting_api.get_bank_transactions(tenant_id, opts).bank_transactions

# Bank Transfers
opts = {
  where: {
    amount: "> 999.99"
  },
  order: 'Amount ASC'
}
xero_client.accounting_api.get_bank_transfers(tenant_id, opts).bank_transfers

NOTE

1. Not all opts parameter combinations are available for all endpoints, and there are likely some undiscovered edge cases. If you encounter a filter / sort / where clause that seems buggy open an issue and we will dig.

2. Some opts string values may need PascalCasing to match casing defined in our core API docs.

   • opts = { order: 'UpdatedDateUtc DESC'}

3. If you have use cases outside of these examples let us know.
