Why do we need your Email Address?
If you are a new customer, we need your email address for 2 purposes. First, we send our confirmation message to your email address. Second, your email address will become the Client ID that you will use in calling the REST API.
If you are a returning customer, you should put down your existing Client ID. We will extend your subscription from the current expiry date. Don't worry - if your subscription has already expired, we will extend it from today.
