The access token is like a user name and password combined. It gives access to our APIs.
When you sign up for a trial account, a trial access token is created for you automatically and sent to your email address. While your account is in trial mode, your token should only be used for testing and evaluation.
When you purchase from us for the first time, the same access token is activated and can then be used for lookups on a live system.
Your developers will need the access token in order to add (integrate) our address search to your application or website.
