Hi, is the deprecated addressbook API still accepting new signups? I tried registering for a BBAuth key and there is no "address book" anywhere in the scopes list. I've got some prewritten code here and would rather not search for some new code that works with the contacts API.
There is no way to register for a new Address Book API key. There is a PHP SDK that will make it easier to transition to the Contacts API, however. Check out the getContacts() method in the SDK, and feel free to post back if you have questions.
