Quickbooks-Ruby

Integration with Quickbooks Online via the Intuit Data Services v3 REST API.

NOTE: If you are looking for the v2 API then you need to use my other library - Quickeebooks:

https://github.com/ruckus/quickeebooks

This library communicates with the Quickbooks Data Services v3 API, documented at:

Data Services v3

Requirements

This is being developed on Ruby REE, 1.9.2 & 1.9.3. Other versions/VMs are untested but stable Rubies should work in theory.

Dependencies

Gems:

• oauth
• roxml : Workhorse for (de)serializing objects between Ruby & XML
• nokogiri : XML parsing
• active_model : For validations

Getting Started & Initiating Authentication Flow with Intuit

What follows is an example using Rails but the principles can be adapted to any other framework / pure Ruby.

Create a Rails initializer with:

QB_KEY = "your apps Intuit App Key"
QB_SECRET = "your apps Intuit Secret Key"

$qb_oauth_consumer = OAuth::Consumer.new(QB_KEY, QB_SECRET, {
    :site                 => "https://oauth.intuit.com",
    :request_token_path   => "/oauth/v1/get_request_token",
    :authorize_url        => "https://appcenter.intuit.com/Connect/Begin",
    :access_token_path    => "/oauth/v1/get_access_token"
})

To start the authentication flow with Intuit you include the Intuit Javascript and on a page of your choosing you present the "Connect to Quickbooks" button by including this XHTML:

<!-- somewhere in your document include the Javascript -->
<script type="text/javascript" src="https://appcenter.intuit.com/Content/IA/intuit.ipp.anywhere.js"></script>

<!-- configure the Intuit object: 'grantUrl' is a URL in your application which kicks off the flow, see below -->
<script>
intuit.ipp.anywhere.setup({menuProxy: '/path/to/blue-dot', grantUrl: '/path/to/your-flow-start'});
</script>

<!-- this will display a button that the user clicks to start the flow -->
<ipp:connectToIntuit></ipp:connectToIntuit>

Your Controller action (the grantUrl above) should look like this:

  def authenticate
    callback = quickbooks_oauth_callback_url
    token = $qb_oauth_consumer.get_request_token(:oauth_callback => callback)
    session[:qb_request_token] = token
    redirect_to("https://appcenter.intuit.com/Connect/Begin?oauth_token=#{token.token}") and return
  end

Where quickbooks_oauth_callback_url is the absolute URL of your application that Intuit should send the user when authentication succeeeds. That action should look like:

def oauth_callback
	at = session[:qb_request_token].get_access_token(:oauth_verifier => params[:oauth_verifier])
	token = at.token
	secret = at.secret
	realm_id = params['realmId']
	# store the token, secret & RealmID somewhere for this user, you will need all 3 to work with Quickeebooks
end

Creating an OAuth Access Token

Once you have your users OAuth Token & Secret you can initialize your OAuth Consumer and create a OAuth Client using the $qb_oauth_consumer you created earlier in your Rails initializer:

access_token = OAuth::AccessToken.new($qb_oauth_consumer, access_token, access_secret)

Getting Started - Retrieving a list of Customers

The general approach is you first instantiate a Service object based on the entity you would like to retrieve. Lets retrieve a list of Customers:

service = Quickbooks::Service::Customer.new
service.company_id = "123" # also known as RealmID
service.access_token = access_token # the OAuth Access Token you have from above

customers = service.query() # Called without args you get the first page of results

# yields

customers.entries = [ .. array of Quickbooks::Model::Customer objects .. ]
customers.start_position = 1 # the current position in the paginated set
customers.max_results = 20 # the maximum number of results in this query set

Under the hood Intuit uses a simple SQL-like dialect for retrieving objects, the above no-arg use of query() issued a Select * From Customer.

You can issue your own query by passing the complete and valid query as the first argument:

customers.query("Select Id, GivenName From Customer")

Each Entity has different fields you can retrieve & filter on. Refer to Intuit documentation for details.

Pagination

Do not pass pagination parameters in your query - pass them as additional options, using :page and :per_page:

# to use the default query
customers.query(nil, :page => 2, :per_page => 25)

# to use a custom query: find customers updated recently and only select a few attributes
query = "Select Id, GivenName From Customer Where Metadata.LastUpdatedTime>'2013-03-13T14:50:22-08:00' Order By Metadata.LastUpdatedTime"
customers.query(query, :page => 2, :per_page => 25)

Retrieving a single object

You can retrieve a specific Intuit object like so:

customer = service.fetch_by_id("99")
puts customer.company_name
=> "Acme Enterprises"

Updating an object

By default updating an object will un-set any attributes that are NOT specified in the update request. That is, the update is NOT sparse by default. Thus, be careful as you might accidentally unset attributes that you did not specify.

Example:

# fetch a Customer to change their name
customer = service.fetch_by_id("99")
customer.company_name = "Neo Pets"
service.update(customer)

In the above example since we retrieved all fields and then just changed a single attribute, we have given the "complete" entity back to Intuit and effectively only the name is changed.

If you don't have the complete object on hand and only want to change a couple of attributes without un-setting what you are not specifying than you want to use a sparse update:

# update a Customer's name when we only know their ID
customer = Quickbooks::Customer::Model.new
customer.id = 99
customer.company_name = "New Company Name"
service.update(customer, :sparse => true)

Generating an Invoice

A complete example on generating a basic invoice:

# Given a Customer with ID=99 lets invoice them for an Item with ID=500
invoice = Quickbooks::Model::Invoice.new
invoice.customer_id = 99
invoice.txn_date = Date.civil(2013, 11, 20)
invoice.doc_number = "1001" # my custom Invoice # - can leave blank to have Intuit auto-generate it

line_item = Quickbooks::Model::InvoiceLineItem.new
line_item.amount = 50
line_item.description = "Plush Baby Doll"
line_item.sales_item! do |detail|
  detail.unit_price = 50
  detail.quantity = 1
  detail.item_id = 500 # Item ID here
end

invoice.line_items << line_item

service = Quickbooks::Service::Invoice.new
service.company_id = "123"
service.access_token = access_token
created_invoice = service.create(invoice)
puts created_invoice.id
=> 234

Notes: line_item.amount must equal the unit_price * quantity in the sales detail packet - otherwise Intuit will raise an exception.

Deleting an Object

Use Service#delete which returns a boolean on whether the delete operation succeeded or not.

service.delete(customer)
=> returns boolean

Logging

Quickbooks.log = true
