Calling this method will perform a verification. If your account includes address cleansing set the CleansedAddress flag to get
additional address information in the result. You can query configuration to get what fields are available to you in each country.
It is also possible to get sample requests from the customer portal.
If you are configured for a sandbox account make sure to call Get Test Entities to get test data for a country you want to try. Sandbox accounts only use these test entities and so trying to verify with any other data will result in no matches being found.
