Prelude: Registering an application key

You should register yourself an application key on the api sandbox.

Go to to sign up.
This URL is your BASE-URL.

Your email doesn't have to be real, but should be if you want to recover your password.

After signing up, you should "Get API Key".

Put in some information, and you should be presented with your Consumer_Key and your Comsumer_Secret. Make a copy of the key and secret.

While you are logged in, you might as well "Create Sandbox Test Account". The "Desired Account Id" should be unique to each bank. You can create as many accounts as you like. Try creating a few with some money in them. And remember the bank those accounts are in, and also the account_id that you used. We will use them later for payment.
