RubyUniversign

RubyUniversign is a Ruby gem for interacting with Universign electronic signature API.

It ease requests to Universign API, documents uploads and following signature state.

This gem is not officialy made by Universign, but was originally created by CapSens for internal usage.

This gem currently integrate electronic signature service, but not other Universign services (timestamping and server stamp).

Installation

Add this line to your application's Gemfile:

gem 'ruby_universign', require: 'universign'

And then bundle

Or install it with:

gem install ruby_universign

And load it with:

require 'universign'

Usage

Configuration:

# if you're using Rails, put this in an initializer
Universign.configure do |config|
  config.endpoint = 'your_universign_endpoint' # Required ...
  config.login    = 'your_login' # Required ...
  config.password = 'your_password' # Required ...
  config.proxy    = 'your_proxy_uri:your_proxy_port' # Optionnal ...
  config.timeout  = 30 # Optionnal if you wanna change the default XMLRPC Timeout ...
end

Then, you can create a transaction like this:

document_from_url = Universign::Document.new(
  name: 'my_contract.pdf',
  url:  'http://www.orimi.com/pdf-test.pdf'
)
document_from_content = Universign::Document.new(
  name:    'another.pdf',
  content: File.open('spec/fixtures/universign-guide-8.8.pdf').read
)

signer = Universign::TransactionSigner.new(
  first_name:      "Signer's first name",
  last_name:       "Signer's last name",
  email:           'test@gmail.com',
  phone_number:    '0101010101',
  success_url:     'https://google.com/',
  signature_field: Universign::SignatureField.new(coordinate: [20, 20], page: 1)
)

transaction = Universign::Transaction.create(
  documents: [document_from_url, document_from_content],
  signers:   [signer],
  options:   { profile: 'default', final_doc_sent: true }
)

transaction.url
# => "https://sign.test.universign.eu/fr/signature/?id=f052e35e-a792-4440-bb67-6b5c3f17aa30"

transaction.transaction_id
# => "9696179e-a43d-4803-beeb-9e5c02fd159b"

# reload transaction data from universign:
transaction = Universign::Transaction.new('9696179e-a43d-4803-beeb-9e5c02fd159b')
# was the transaction signed by the user ?
transaction.signed?

The gem also supports the updated way of creating multiple signature fields per document:

doc_1 = Universign::Document.new(
  name:    'one.pdf',
  content: File.open('spec/fixtures/universign-guide-8.8.pdf').read,
  signature_fields: [
    Universign::SignatureField.new(coordinate: [20, 20], page: 1, signer_index: 0),
    Universign::SignatureField.new(coordinate: [80, 20], page: 1, signer_index: 0)
  ]
)

doc_2 = Universign::Document.new(
  name:    'two.pdf',
  content: File.open('spec/fixtures/universign-guide-8.8.pdf').read,
  signature_fields: [
    Universign::SignatureField.new(coordinate: [100, 120], page: 4, signer_index: 0),
  ]
)

transaction = Universign::Transaction.create(
  documents: [doc_1, doc_2],
  signers:   [signer],
  options:   { profile: 'default', final_doc_sent: true }
)

Universign::Document

It can be created with either your file's content or your file's url.

Universign::SignatureField

Nothing much to say here. It follows Universign's signature field.

You can pass the coordinates of the signature or the name of the field.

If the PDF already contains a named signature field, you can use this parameter instead of giving the coordinates (which will be ignored). If the name of this field does not exist in the document, the given coordinates will be used instead.

Universign::TransactionSigner

• success_url is where your user will be redirected after signing the documents.
• phone_number is optional. If you don't specify it, Universign will ask the user for it at the time of the signature.
• email is optional, unless you want to use transaction's final_doc_sent option (to send signed documents to user's email).

Universign::Transaction

To start a transaction with Universign, you only require documents and signers.

Options are, as the name imply, optional ! Available options are (snake_case of Universign's names):

custom_id
description
handwritten_signature_mode
certificate_type
language
identification_type
handwritten_signature
profile
final_doc_sent
final_doc_requester_sent
chaining_mode

Default options are:

{
  handwrittenSignatureMode: 1,
  identificationType:       'sms',
  language:                 'fr',
  certificateType:          'simple'
}

For more informations on theses options, see Universign's official documentation

Once your transaction is created:

• url is where you must redirect your users for them to sign
• transaction_id is the id you must save to retrieve it later. You can request up-to-date informations from Universign with Universign::Transaction.new(transaction_id).
• signed? returns a boolean that tells you if the transaction is signed, or not !
