I have savon version =>1
and my code is here
require 'savon'
client = Savon::Client.new "http://midoffice.makemytrip.com/MMT_Webs_CreateIncident/MMT_Webs_CreateIncident.asmx"
response = client.do_simple do |soap|
soap.body = {
:FirstName =>"ravendra"
}
end
and it gives us
undefined method `do_simple' for #<Savon::Client:0xb6c87178>
