LexisNexisInstantAuthenticate

Generate & Score Instant Authenicate quizes using Lexis Nexis SOAP API.

This gem originally started as a simple Savon.rb service, however, it was quickly made clear that the LN SOAP API has some rough edges that require some specialized changes. The main patch was around authentication. This gem monkey patches the Akami::WSSE#wsse_username_token method to include the cleartext password along with the digest auth.

This gem also does not leverage the WSDL from LN, even though it does import it into Savon. Savon has problems parsing the WSDL correctly and as such does not provide a reliable interface.

Add this line to your application's Gemfile:

gem 'lexis_nexis_instant_authenticate'

And then execute:

$ bundle

Or install it yourself as:

$ gem install lexis_nexis_instant_authenticate

###Create a client.

@client = LexisNexisInstantAuthenticate::Client.new(username: ENV['LEXIS_UN'], password: ENV['LEXIS_PW'], flow: "LEXIS_FLOW", transaction_id: SecureRandom.uuid)

Options:

• username: Lexis Nexis supplied username. Typically, "#{account_id}/#{username}"
• password: Lexis Nexis supplied password.
• flow: Name of workflow.
• transaction_id: Optional GUID. This must be the same string between quiz creation & quiz scoring requests. If you do not pass one in on quiz creation, SecureRandom.uuid will be used and returned with the generated quiz. That same string must be sent when scoring quiz.

###Generate a quiz.

  response = @client.create_quiz({first_name: "Joe", middle_name: "L", last_name: "Smith", ssn: "123456789", dob: {day: "01", month: "01", year: "1950"}})
  if response.success?
    return response
  else
    return response.status
  end

Response will have:

• response.questions
• response.id
• response.transaction_id

###Scoring Responses The score_quiz method expects the following arguments:

• transaction_id This is the GUID that you called the create_quiz method with or the GUID that was generated for you.
• responses This is an array of hashes in the form of {question_id: 1234, choice_id: 4321}

  response = @client.score_quiz(transaction_id, Array(@responses).map(&:with_indifferent_access))
  if response.success? && response.pass?
    return true
  else
    return response.status
  end

Response will have:

• response.success?
• response.pass?
• response.score
• response.proofing_response

• Write Tests
• Transition to actual WSDL from LN.
• Refactor Response Object.
