Ruby gem for creating SEPA XML files

We love building payment applications! So after developing the DTAUS library for Ruby we move on with SEPA.

Features

This gem implements the following two messages out of the ISO 20022 standard:

• Credit Transfer Initiation (pain.001.003.03, pain.001.002.03 and pain.001.001.03)
• Direct Debit Initiation (pain.008.003.02, pain.008.002.02 and pain.008.001.02)

It handles the Specification of Data Formats v2.7 (2013-11-04).

BTW: pain is a shortcut for Payment Initiation.

Requirements

• Ruby 2.2 or newer
• ActiveModel 3.1 or newer (including 6.0)

Installation

gem install sepa_king

Validations

You can rely on our internal validations, raising errors when needed, during message creation. To validate your models holding SEPA related information (e.g. BIC, IBAN, mandate_id) you can use our validator classes or rely on some constants.

Examples:

class BankAccount < ActiveRecord::Base
  # IBAN validation, by default it validates the attribute named "iban"
  validates_with SEPA::IBANValidator, field_name: :iban_the_terrible

  # BIC validation, by default it validates the attribute named "bic"
  validates_with SEPA::BICValidator, field_name: :bank_bic
end

class Payment < ActiveRecord::Base
  validates_inclusion_of :sepa_sequence_type, in: SEPA::DirectDebitTransaction::SEQUENCE_TYPES

  # Mandate ID validation, by default it validates the attribute named "mandate_id"
  validates_with SEPA::MandateIdentifierValidator, field_name: :mandate_id
end

Beware: The SEPA::IBANValidator is strict - e.g. it does not allow any spaces in the IBAN.
