IContact api integration -"The application was not recognized. Possible reasons are: the Api-AppId was entered incorrectly; the application is not registered for that user.

[Rajendranar14]

I have code like this,

require 'icontact-api'

class BetaApi < Icontact::Api

attr_accessor :key, :secret, :domain

API_USERNAME='my production Icontact user name'
API_PASSWORD='my production Icontact password'
API_KEY = 'My production app Id 32 key'
API_SECRET = 'My production app password(secret password) '
DOMAIN = "http://app.beta.icontact.com/icp"

def initialize(username = BetaApi::API_USERNAME, password = BetaApi::API_PASSWORD)
super(username, password)
self.key = API_KEY
self.secret = API_SECRET
self.domain = DOMAIN
end

end

@api = BetaApi.new
p @b= @api.get('/a')
p @c= @api.post('/a/1373573/c/9020/', 'test@gmail.com')

But I'm getting the below error, here what's wrong? Please help me ...
