Public Instance Methods
WorldPay
only supports a single address field so we have to concat together - lines are separated using
# File lib/offsite_payments/integrations/world_pay.rb, line 67 def billing_address(params={}) add_field(mappings[:billing_address][:zip], params[:zip]) add_field(mappings[:billing_address][:country], lookup_country_code(params[:country])) address = [params[:address1], params[:address2], params[:city], params[:state]].compact add_field('address', address.join(' ')) end
# File lib/offsite_payments/integrations/world_pay.rb, line 112 def callback_params(params={}) params.each{|k,v| add_field("M_#{k}",v)} end
# File lib/offsite_payments/integrations/world_pay.rb, line 116 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 76 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 85 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 108 def response_params(params={}) params.each{|k,v| add_field("C_#{k}",v)} end
Add a time window for which the payment can be completed. Read the link below for how they work support.worldpay.com/kb/integration_guides/junior/integration/help/appendicies/sjig_10100.html
