This gem is a drop-in replacement for the Interfax gem, with the exception that this one runs on Ruby 1.9.

Below is an updated copy of the original Interfax README.

This library is a wrapper for the interfax.net fax service. For now, you can do the following:

• Send HTML/PDF faxes
• Query the status of a sent fax
• Retrieve a list of incoming faxes
• Get the image for a sent fax

If you're willing to help, just drop me a line.

gem install interfax19

To use with Bundler, add the following line to your Gemfile:

gem "interfax19", require: "interfax"

Create a class, inherit from Interfax::Base and set authentication parameters:

class OrderFax < Interfax::Base
  self.username = "my_interfax_username"
  self.password = "my_interfax_password"
end

Creating a fax is simple regardless of if you're sending PDF or HTML content:

Creating an HTML fax:

fax = OrderFax.new(:html).contains("<h1>test</h1>").subject("test").to("+4923456123456")

Creating a PDF fax:

fax = OrderFax.new(:pdf).contains(File.read('/files/document.pdf').subject("test").to("+4923456123456")

It is possible to specify more than one receipent:

fax = OrderFax.new(:html).contains("<h1>test</h1>").subject("test").to(["+4923456123456","+4943254324312"])

To get a summary before sending, just call summary on it which returns a hash:

fax.summary

Finally:

result_id = fax.deliver

To get all faxes:

faxes = OrderFax.all

You can limit the number of received items with an optional parameter:

faxes = OrderFax.all(10)

To find a specific fax:

OrderFax.find(123456789)

or get more than one at once:

OrderFax.find(123456789,234567890)

To get a list of incoming faxes, you can either use the base class:

Interfax::Incoming.username      = 'my_interfax_username'
Interfax::Incoming.password      = 'my_interfax_password'
Interfax::Incoming.limit         = 15    # optional, default 100
Interfax::Incoming.mark_as_read  = false # optional, default false

# fetch unread incoming faxes
faxes = Interfax::Incoming.new

If you want you can define your own subclass -- useful for keeping authentication info handy -- you can do so:

class IncomingFaxes < Interfax::Incoming
  self.username = 'my_interfax_username'
  self.password = 'my_interfax_password'
end

# fetch all incoming faxes
faxes = Interfax::Incoming.all

There are four methods for fetching incoming faxes:

#all               - Fetch all incoming faxes 
#unread            - Fetch unread incoming faxes
#account_all       - Fetch incoming faxes for all users on your account
#account_unread    - Fetch unread incoming faxes for all users on your account

The account_ methods require that you have admin privileges. For more information, see the Interfax API documentation.

The Interfax::Incoming methods described above return an array of instances of the class you called it on. If you're using the Interfax::Incoming class you'll get those. If you use a subclass, we'll instantiate that class and return an array of those.

In either event, call the #image method to fetch the PDF/TIF of the fax as a string, suitable for writing to the filesystem in the normal fashion.

# Assume you've defined a sublcass as above
all_faxes = IncomingFaxes.all
all_faxes[0].image # return the first fax's image

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
