A simple Ruby client for the Roku Web Service Api.

Installation

Add this line to your application's Gemfile:

gem 'roku-iap'

And then execute:

$ bundle

Or install it yourself as:

$ gem install roku-iap

Usage

Initialize a client with your Roku API key:

client = Roku::Iap::Client.new 'roku_api_key'

Call any of the following methods (outlined in the Roku sdk docs):

result = client.validate_transaction 'some-transaction-id'
result = client.validate_refund 'some-refund-id'
result = client.cancel_subscription 'some-tranasaction-id', 'cancellation_date', 'partner_ref_id'
result = client.refund_subscription 'some-transaction-id', 'amount', 'partner_ref_id', 'comments'

Response

The returned Roku::Iap::Response object has underscored attributes correlating to the xml returned by the Roku API. successful? can be called on the result to confirm that the response contains no errors.

result = client.validate_transaction 'some-transaction-id'

if result.successful?
  puts result.amount          #"9.99"
  puts result.purchase_date   #"2014-11-03T00:07:23"
else
  puts result.error_message   #"Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)."
end

Exceptions

Non-200 status code responses will raise a Roku::Iap::Exceptions::General exception, and are distinct from errors returned by the Roku API (which you may call result.error_message to elaborate upon). A 404 can be presumed to be a nil devtoken parameter, and will raise a Roku::Iap::Exceptions::InvalidCredentials exception.

All defined exceptions inherit from Roku::Iap::Exceptions::Exception, and can be handled as:

begin
  result = client.validate_transaction 'some-transaction-id'
rescue Roku::Iap::Exceptions::Exception => e
  # enqueue to try again later
end
