Making the custom setting that stores the address verification data Protected. Since you cannot change the type, I had to create a new one and delete the old one.
Removing the old custom Address Verification Settings file.
Don't echo back auth ID and auth token in VF page.
Making Addr_Verification_Settings__c transient.
Fixing test. It should use the getter now.
Making addr verif request only if checkbox and credentials are set. Don't populate response with error message otherwise.
We are checking if the checkbox is checked now (how's that for redundancy), so we'll have to check it in the tests.
Putting back the Address_Verification_Setting object to avoid build failure (dependencies not resolving correctly). Marking all as deprecated.
Missed it.
