FedEx: Authentication Failed with test account - soap

Question

I'm trying to integrate FedEx with my application. I created a test account.
When I send RateRequest I got a response Authentication Failed (code is 1000).
I use v10 of Fedex Rate service. For SOAP I use Savon ruby gem.
Here is code I use:
require 'rubygems'
require 'savon'
TEST_URL = 'https://wsbeta.fedex.com:443/web-services/rate'
client = Savon::Client.new do
wsdl.document = File.expand_path("../rate_wsdl.xml", __FILE__)
wsdl.endpoint = TEST_URL
end
client.request "RateRequest" do
soap.body = {
'WebAuthenticationDetail' => {'Key' => KEY, 'Password' => PASSWORD},
'ClientDetail' => {'AccountNumber' => ACCOUNT_NUMBER, 'MeterNumber' => METER_NUMBER},
'RequestedShipment' => {
'PackagingType' => 'FODEX_BOX',
'Shipper' =>
{'Address' => {'PostalCode' => '90210', 'CountryCode' => 'US', 'Residential' => 'true'}
},
'Recipient' =>
{'Address' => {'PostalCode' => 'KIP 1J1', 'CountryCode' => 'CA', 'Residential' => 'true'}
},
'RateRequestTypes' => 'ACCOUNT',
'PackageCount' => '1',
'RequestedPackages' => {
'Weight' => {'Units' => 'LB', 'Value' => '7.5'},
'Dimensions' => {'Length' => '15', 'Width' => '10', 'Height' => '5', 'Units' => 'IN'}
}
#'LabelSpecification' => ''
}
}
end
I googled a lot about it. Some people had the same problem. People say it can be caused because of lack of permission of address validation, but I can't find how I can disable it if so.
I am sure that all credentials are OK (account number, meter number, key, password).
Also I tried "https://wsbeta.fedex.com:443/web-service" for endpoint url as well.

Answer 1

Figured out of was wrong. I sent invalid SOAP request. Thanks to SOAPUI tool, it helped me to validate my request.
