WorldPay
supports two different test modes - :always_succeed and :always_fail
# File lib/offsite_payments/integrations/world_pay.rb, line 50 def initialize(order, account, options = {}) super if OffsitePayments.mode == :test || options[:test] test_mode = case options[:test] when :always_fail 101 when false 0 else 100 end add_field('testMode', test_mode.to_s) elsif OffsitePayments.mode == :always_succeed add_field('testMode', '100') elsif OffsitePayments.mode == :always_fail add_field('testMode', '101') end end

# File lib/offsite_payments/integrations/world_pay.rb, line 107 def callback_params(params={}) params.each{|k,v| add_field("M_#{k}",v)} end
# File lib/offsite_payments/integrations/world_pay.rb, line 111 def combined_params(params={}) params.each{|k,v| add_field("MC_#{k}",v)} end
WorldPay
only supports a single name field so we have to concat
# File lib/offsite_payments/integrations/world_pay.rb, line 71 def customer(params={}) add_field(mappings[:customer][:email], params[:email]) add_field(mappings[:customer][:phone], params[:phone]) add_field('name', "#{params[:first_name]} #{params[:last_name]}") end
Support for a MD5 hash of selected fields to prevent tampering For further information read the tech note at the address below: support.worldpay.com/kb/integration_guides/junior/integration/help/tech_notes/sjig_tn_009.html
# File lib/offsite_payments/integrations/world_pay.rb, line 80 def encrypt(secret, fields = [:amount, :currency, :account, :order]) signature_fields = fields.collect{ |field| mappings[field] } add_field('signatureFields', signature_fields.join(':')) field_values = fields.collect{ |field| form_fields[mappings[field]] } signature = "#{secret}:#{field_values.join(':')}" add_field('signature', Digest::MD5.hexdigest(signature)) end
WorldPay
supports the passing of custom parameters prefixed with the following: C_ : These parameters can be used in the response pages hosted on WorldPay’s site M_ : These parameters are passed through to the callback script (if enabled) MC_ or CM_ : These parameters are availble both in the response and callback contexts
# File lib/offsite_payments/integrations/world_pay.rb, line 103 def response_params(params={}) params.each{|k,v| add_field("C_#{k}",v)} end
