What is Quickbook?
Install gems omniauth and omniauth-quickbooks to authenticate with quickbooks.
By default, the gem quickbooks-ruby will be in production mode but you can run it in other mode (development or testing).
Create a rails initializer and set the OAUTH_CONSUMER_KEY and OAUTH_CONSUMER_SECRET properly and set the callback in the routes in order to inform rails about the request.
You can set the OAuth access credentials with four fields access_token, access_secret, company_id, token_expires_at to avoid connecting to Quickbook often.
After, all the important and basic setup is done now its time to learn how to generate invoices for the user. Without an user generating invoices makes no sense. Hence, the first thing is to know the user. There are two possible cases for this:
1) If the user does not exist in quickbook, create the user and generate the invoice.
2) If the user already exists in quickbook, update the user and generate the invoice.
If the user does not exist then instantiate a Service object on the Customer and create it.
... def build_user_information service = Quickbooks::Service::Customer.new service.access_token = access_token service.company_id = company_id quickbook_customer = Quickbooks::Model::Customer.new quickbook_customer = set_user_information quickbook_customer service.create(quickbook_customer) end def set_user_information quickbook_customer # Name quickbook_customer.given_name = quickbook_customer.display_name = quickbook_customer.print_on_check_name = quickbook_customer.fully_qualified_name = "First Last" # Email quickbook_email = Quickbooks::Model::EmailAddress.new quickbook_email.address = "[email protected]" quickbook_customer.primary_email_address = quickbook_email # Phone Number quickbook_phone_number = Quickbooks::Model::TelephoneNumber.new quickbook_phone_number.free_form_number = 9876543210 quickbook_customer.primary_phone = quickbook_phone_number # Address quickbook_address = Quickbooks::Model::PhysicalAddress.new quickbook_address.line1 = "line1" quickbook_address.line2 = "line2" quickbook_address.city = "city" quickbook_address.country = "country" quickbook_customer.billing_address = quickbook_address quickbook_customer end
The above piece of code has two methods,
The first method is to create the user in the quickbook.
The second method is to set the data using an object of Quickbook’s customer.
service.create(quickbook_customer) will create a new quickbook customer with an id as its primary key, say 21 in this case.
If the user already exists in quickbook then get the customer and update it.
... def update_user_information service = Quickbooks::Service::Customer.new service.access_token = access_token service.company_id = company_id quickbook_customer = service.fetch_by_id(21) quickbook_customer = set_user_information quickbook_customer service.update(quickbook_customer) end
There are couples of things that you can play with the service object
users = service.all
users will be an array with all the objects of the service(customer in our case)
users = service.query()
It will be a SQL like structure to retrieve objects.
In the next post there will be a procedure to generate the invoices for the created customer.
